Finally we could solve the problems related to the gid list. They were caused
by the implantation of a new e-mail domain at the university and its
coexistence with the old e-mail domain. Sorry for the inconveniences and thanks
for your patience.

Hi GiD Team
I'm using version 6.3.0b and would like to know what the present version can
do more than my version, so I can decide if it is worth upgrading i.e. is
there a version history document ?

Good morning everybody,
What are the last news from GID ? Is the last GID version 7.4.6b ?
Write you soon.
G.W.R. Geis

Last available beta version for Windows is the 7.5.3b

This is a detailed list of new features and corrected bugs from the 7.2 official version, until 7.5.0b beta version.

Regards
Enrique Escolano

      What is new from version 7.2 to beta version 7.5.0b 

      NEW FEATURES - PREPROCESS

        a.. New mesh renumber option. Setting the variable 'RenumberMethod' to 1, after generate a mesh, the nodes are renumbered with a Reverse Cuthill-McKee algorithm. (setting 0 the old renumber method is applied, and setting -1 the mesh is not renumbered). For future versions new algoritms can be included.

No, there is no document explaining this. It is just an ascii file that stores
the view information of GiD.

A view can be stored and loaded from the menubar View->View->Read/Save and can
be used independently of the model (but related to its size: it is not the same
a zoomed view of a printed circuit where the scale is from order 1e-3,
milimeters, and a zoomed view of an airplane, where the domain is of order 1e3,
(km?)). Just to get the idea. 

The abreviations stand for:

 x - left and right planes
 y - top and bottom planes
 z - near and far planes
 e - margin between view - model box
 v - rotation vector
 r - rotation factor
 m - rotation matrix
 c - figure center
 pd - perspective distance
 pno - perspective near plane
 pfo - perspective far planes
 pf - perspective factor
 pv - perspective view

Hope this helps,

miguel

Dear GID Team,

I am developing a problem type to work with thermal-mechanics problems.

In my models, I need a boundary condition that uses some point's coordinates: x, y and z. So, my problem is:

I need put a "pick" button in a boundary condition window in GID. When I'll click in this button, it give me the coordinates x, y and z of the point clicked, just like occurs in the "copy" and "move" GID's windows.

Is it possible? I need information about the CND and BAS files to make it.

If it is possible only using TCL, how do I do it?

Thanks a lot for the attention.

It not exists in our  *.cnd file a "coordinates" field (to show a pick point button)
Maybe for future versions can add this feature as standard.

At this moment only is possible using Tcl/Tk. They are two options:
a) - Completly write your own alternative "conditions window" (can see the Tdyn problemtype as a sample)
b) - Change the central part of our window: read this paper, about "Tkwidget" of the last GiD Conference: http://www.gidhome.com/2004/papers/p236.pdf (can se the Ramseries problemtype as a sample)

can also use this two Tcl procedures (defined inside scripts/dev_kit.tcl)
proc GidUtils::GetCoordinates { { WarnLineMsg "" } { JoinNoJoin  "Join" } }
# returns the coordinates x y z Or null selecting from the screen
# GidPriv(selcoord,id) store the point id (-1 nothing selected, 0 new point, >0 point id)
# to get the number of a existent point, cal also use PickEntities
# JoinNoJoin can be "Join" or "NoJoin"

proc GidUtils::PickEntities { type selectmode }
# type can be "Points" "Lines" "Surfaces" "Volumes" "Dimensions" "AllTypes" "Nodes" or "Elements"
# selectmode can be "single" or "multiple"
# for AllTypes selection returns some as 
# Points 19 23 Lines 28:29 32:33 37 Surfaces 1 6 21:22 Volumes 1 Dimension 1:2
# or for mesh entities some as Nodes 236 244 Elements 4122 4130 4152 4165

In othe hand, I recommend to use 3 separated *cnd standard fields for x, y, z values, 
and expect this new feature appear in next beta versions.

win2000 gid6.3.0b

Hi Gid team

The attached model is a square with rounded corners produced from a square &
then performing an arc tangents operation at each corner. I have then
collapsed the lines to give me just 1 line instead of 4 lines and 4 arcs.
Question: is it possible (undo is not an option in my real case) to break
this line back into it's constituent parts again (points lines & arcs)?
if I do an edit nurbs line it shows me all the original points etc how can I
get them back again?

best regards

Hi

I am using the template file creation feature. Currently I have it 
configured that way to let print out the element numbers and the nodes 
of those volume elements a volume condition is applied to and of those 
surface elements any surface condition is applied to. Now it 
occasionally happens that an affected surface element is also part of an 
affected volume element. Since surface and volume elements have 
different element numbers, it seems there is no way tell that some of 
those surface and volume elements belong to each other. However, this 
would be important to know for my program. Thanks for any suggestions.

Sebastian

I don't understand well your problem.
Maybe your own program can detect (comparing the node numbers) that a
surface element is the face of a volume element

Yes, I already thought of this, but I wanted to avoid to write such a 
algorithm myself. I hoped that each face element "knows" that it is part 
of a certain volume element and it would be possible to simply retrieve 
the ID of this volume element like

*set var surfaceElem = 0
*Set elems(Quadrilateral)
*loop elems
*set var surfaceElemNum = surfaceElemNum + 1
Face Element *surfaceElemNum --> Volume Element *higherOrderElemNum
*end elems

I guess these volume element IDs are available in GID's tcl scripts, 
however, such a command *higherOrderElemNum isn't probably implemented  
yet, so that the user could also access to this information.

Cheers

Sebastian

...
It seems than you don't explicitly  need to generate quadrilaterals and
hexahedras.
you must define a condition "over surfaces" to be applied "over face
elements".
Then you only need to generate hexahedras, but not quadrilaterals (default
option), and the condition only mark some element face.

and you must use a bas loop like this:

*set cond mycond elems
*loop elems *onlyincond
  Face element nodes: *globalnodes
  Volume element: *elemsnum
*end elems

Note: In other hand, GiD entities internally  doesn't store pointers to
their higher entities,
then it's not easy/fast to use a command like *higherOrderElemNum

It doesn't exists any funcion to automatically  break a curve on this
"special" points (hight curvature changes, etc).
And you don't know the exact curve paremeter to manually divide it.

Maybe for next versions we will remove this "join tangent lines" filter from
the "Collapse" function, and put as a separated funcion.
We will also think about to implement some function to detect and/or divide
curves/surfaces from this special points.

Thank you, I look forward to the new feature.
Mean time there is a work around in that I can use utilities:list:lines &
then cut & paste the data into a text editor, remove the unwanted data and
add a header of geometry create point and put escape at the end.
Unfortunately this doesn't always want to work, see attached batch file,
when loaded into GiD it tells me I have an error and stops after reading
line 10 ?
Is there an undocumented format for the batch file?

Before read this batch, set  the general preference (utilities preferences)
create new point: to always

In any case, in general, you cannot reconstruct a line only from his control points.

Hi Gid Team:

I’m using 7.2 trial version for a heat transfer problem in a plastic
molding injection in 3d. I did the model in the same GID, because the
.iges model can’t be meshed with structured elements, the piece is a
kind of ring, which is surrounded by a steel mold.

I want to do a structured mesh with brick elements, but my problem is
when I created contacts volumes between the plastic and the mold,
because when GID do the mesh, this has distortionated elements in the
plastic, all completed outside the model, but in the mold and the
contact’s elements are OK . I tried to do the mesh without the contact
elements and it works ok, the plastic and mold elements are good, the
problem is only when the contact volumes are in the draw.

Try to download the last 7.5.3b beta version. The are solved some problems related with contact and structured mesh generation.

In other hand, I recommend to avoid the use of "GiD contacts" if they are not really necesaries. 
A "GiD contact" is like a mesh restriction to create two meshes with a one-to-one nodes relation. Is this necessary for your analysis?

Hi

I am trying to create batch file which will create
project and than save it. It also saves calculation
file.

The problem is when gid (gid -b filename) is
processing this file it stops at some point saying
(info window):
Last line read 115: in file 'D:	estatch_template3':
//Yes
//

The batch file is longer about 160 lines and I do not
know why gid stops processing it.
When I use "Utilities->Graphical->Read Batch Window"
file is processed in its full length so I know it is
working

Thanks

Dear Gid-Users,

what I have is a surface-mesh. Now I want to copy this mesh by extruding
from surface- to volume-elements, but the surface-elements are no longer 
nessesary. My question is, if there is any possibility to customize
gid, so that gid deletes the surface-elements by its own. Perhaps this
may be possible by changing some tcl-file like CopyMain.ui.tcl. But I
dont know how to do. I'll be thankful for any suggestions.

best regards
Christian Großmann

There is a very bad idea to directly directly modify the GiD scripts,
because the next update you will lost your own changes.

Using the last GiD beta versions, it's possible to customize a "macros
toolbar" to call your own Tcl/Tk procedure from a  button.

(but I think that is not interesting to create your own copy window than
after extrude, only to delete undesired elements)

Hello, GiD users!

I have following situation:
A shell script generates a batch file for GiD (see below).
This batch file should read a number of result files and create a 
animation file like animation.gif.

My two problems running the batch file are:

1. GiD executes the batch files lines without waiting for the result of 
previous line. So commands are overlapped and animation is not 
generated. Some idea how to solve the problem?

2. Once (1.) is solved. Is it possible to run GiD without window 
(background running) for that purpose?

Thank you in advance for any suggestion

Hello, Rafael,
As i see from your script file, it seems that you use a different mesh for
every simulation step. Is that right?
I'm implementing this into GiD, and a 'very preliminary' version is
incorporated into GiD v. 7.5.3b.

If you enable the right buttons menu (just by clicking with the right mouse
button over a toolbar, a menu with the option 'configure toolbars' appears; in
this window select the 'right buttons' and click on the radio button 'outside'
or 'inside, so that this right buttons menu pops up), after changing to post
process,please select the 'Files->ReadMultiple'. In the file dialog box, now
select the files (with click and shift-click/ctrl-click) you want GiD to read,
for instance from '...
Thank you Miguel for your email.

Yes, my mesh is "moving" with each simulation step. So, I have at every 
step(certain number of them) a mesh file and a result file.

I tested before and also now again the feature "ReadMultiple" in GiD v. 
7.5.3b for Linux.
GiD read all files. However, doing the animation, I get only the first 
picture in a gif file. Not an animation of all result files.

Now coming back to my batch file. I found why it did not work sometimes:
Reasons:
Case 1:
If the gif file is existing, GiD asks about overwriting or not in the 
lines above the command line. Unfortunately, I have no chance to tell 
GiD nothing, because it's busy finishing the batch file. So now, 
everytime I delete the gif file and do it again. It works nice.
It would be nice, if you can put a checkbox in the animation window like 
"overwrite animation file if existing" or something like this.

Case 2:
When I am using GiD on the calculation server directly the batch file 
works fine.
When I am using GiD trough a (remote) ssh connection, then the commands 
in the batch file get overlapped.
Nice if there is a GiD command for batch files to sleep for some time. Like:

escape escape escape escape
postprocess
escape escape escape escape
sleep 100  ## sleep executing the batch file until commands before got 
finished.
.
.
.

Thank you again
I will be watching the new feature release!

Regards,
Rafael

How are you reading the batch file?
options are:
a) Utilitities->Graphical->Read batch window
b) Files->Import->Batch file
c) gid.exe -b+g "batchfile"

Probably you are using the 'b' option. Try also 'a'

Is it possible to run GiD from the command line (read GiD help about
'Invoking GiD').
The -n parameter is to start without window
gid.exe -b "batchfile" -n
but then it's not possible to create any image (or animation). It's
necessary to have a window, and activate also graphics +g
gid.exe -b+g "batchfile"

What's your GiD version? (Help->About)

Thanks Enrique.

yes, I read the GiD help about invoking GiD. I was wondering if for 
creating an image or animation was possible with parameter -n or -n2.
Now, I know: that is not possible.

To your option question:
Local:
a) works perfect
b) does not work (commands get overlapped)
c) works perfect

Unfortunately very often I have to finish some work out of office. So i 
use ssh.
Remote:
a) does not work*
b) does not work*
c) does not work*

*that executing of batch file lines is faster than the processing time 
of each line itself. For example. In my batch file, the command 
"postprocess" take (remotly -ssh connection) long time, during this time 
other batch file lines are also executed.

I guess it is a speed problem. That is why I was asking for a "sleep" 
command so that I can break or sleep my batch file at some places.

Thank again

Maybe you can create another aditional surface mesh: the boundary of the volume elements.
This command is not included in any menu. Must write this in the lower command line:
escape escape escape meshing createboundary

Then it's created in the current layer to use a triangle mesh (it's not created any new node)
If I understod well your question, the nodes used by this boundary triangles, are your desired nodes.
(you can delete the previous tetrahedras, and lonely nodes, and export the remaining mesh)

Good morning,

I wish assign properties to a mesh.
In particular, there is no problem to assign properties (Id number in
the GID msh file) to surface elements and nodes elements but I do not
have found how to assign properties to the linear elements (a dimension,
a linear resistivity...)
of a mesh.

Is there any solution to this problem ? Is there an problem type example
I could study ?

Thank you,

G.W.R. Geis

In general, it is a bad idea to assign conditions directly over mesh
entities. It's better to assign over the geometric entities, and
then generate a mesh.!!

There is not any particularity to assign conditions to line elements.
Are you sure that you have line elements (2 noded elements, or 3 noded for
quadratic case) ?
Maybe you trying to assign to the edges of a surface mesh.!!

See help about Customization->Conditions file:
An important characteristic of the conditions is that they must define over
what kind of entity are going to be applied, i.e., over points, lines,
surfaces, volumes or layers and over what kind of entity will be
transferred, i.e., over nodes, over face elements or over body elements.

CONDMESHTYPE:
  a.. over nodes means that the condition will be transferred to the nodes
contained in the geometrical entity where condition is assigned.
  b.. over face elements If this condition is applied to a line that is the
boundary of a surface or to a surface that is the boundary of a volume, this
condition is transferred to the higher elements, marking the affected face.
  c.. over body elements If this condition is applied to lines, it will be
transferred to line elements. If it is assigned to surfaces, it will be
transferred to surface elements. If in volumes, to volume elements.
If you have line elements, you probably must define the condition as
CONDMESHTYPE:: over body elements
If you have triangles or quadrilaterals, you probably must define the
condition as  CONDMESHTYPE:: over face elements, to select only some faces
of this elements

Update your GiD version to last 7.5.3b beta version (they have some new
feature to directly assign conditions over face elements).

You can download some interesting problemtypes (Nastran, RamSeries,
Tdyn,...) from the GiD menu:
Data->Problemtypes->Internet retrieve...

Hello,

Is there a Tcl command which returns the number (used in the GID mesh

a number used in the GID mesh file ?

Thank you in advance.

G.W.R. Geis

Read GiD help about Tcl-Tk extension - Info function
The Tcl command: 
GiD_Info materials
returns a list of the current material names, then to get the name of the 1st material, must use for example: 

set i 1
lindex [GiD_Info materials] [expr $i-1]

or to get the number of the material "matname"

set matname "steel"
expr [lsearch [GiD_Info materials] matname]+1

 If you have a geometrical model:
Must create some line to connect this parts, and re-generate the mesh.

If you have only two imported meshes:
By default GiD doesn't include any tool to directly create elements (because
we don´t promote the direct mesh manipulation)
but it's easy with a little of Tcl/Tk code to add this feature. Can see a
tutorial about how to create "Tool of mesh edition" at
http://www.gidhome.com/2004/material_courses.subst
 I attach the "problemtype" created on this tutorial. Must unzip inside
/problemtypes, and load from
the Data->Problemtype menu
Then is possible to manually create nodes and triangles or quadrilaterals
(no line elements, but it's easy for you to add)

Hello,
Studying the Nastran problem type, I noticed that its material window is
not the same than the classical "Material" window of GID. In particular,
it is not possible to assign the materials to the elements : whenever
ASSIGN is pressed the sentence "This material or table cannot be
assigned" appears !
This function should be useful for my problem type, but I do not
understand how it works (especially, I do not understand how the
NastranPostCmdAssignMat procedure is called).
If somebody uses the Nastran problem type for these own problems, I
would be interested by knowing more about this function.

Thank you,

Last GiD beta versions have new undocummented procedures for this pourposes: GiD_DataBehaviour  and GiD_ConditionBehaviour

proc GiD_DataBehaviour {data_t name args}
proc GiD_ConditionBehaviour {name args}

Can see as sample, the related Nastran problemtype

# -----------------------------------------------------------------------------
# GiD_DataBehaviour --
#
#   This command controls properties of data windows for materials and
#   conditions (not currently implemented). For materials we can modify 
#   the behaviour of assign, draw, unassign, impexp, new, modify and delete.
#   We can also specify the entity type list in assign option throught the 
#   cmds geomlist and meshlist.
#
#   Syntax:
#
#     GiD_DataBehaviour data_class name ?cmd? proplist
#
#     data_class could be: "material" if we want to modify the behaviour of a
#     particular material if whole book must be modified the data_class should
#     take the value "materials". Depending on the value of data_class name
#     takes the value of a material's name or a book's name. Argument cmd can
#     take one of the values: show, hide, disable, geomlist and meshlist.
#     Argument proplist is a list of options or entity type. When cmd is show,
#     hide or disable then proplist could a subset of {assign draw unassign
#     impexp new modify delete}. The command show make the option visible,
#     if the value is hide then the option is not visible and when the value is
#     disable then the option is visible but unavailable. When cmd if geomlist
#     then then property list can take a subset of {points lines surfaces volumes}
#     and define the entities that can get the material assigned when in geometry
#     mode, if the value of cmd is meshlist the proplist can take the value
#     elements (only elements can gets a material assigned in mesh mode). 
#
#   Examples:
#
#     GiD_DataBehaviour materials Table geomlist {surfaces volumes}
#     GiD_DataBehaviour materials Solid hide {delete impexp}  
#
#  Note: GiD_DataBehaviour is only implemented for material and books of materials.
# -----------------------------------------------------------------------------

# GiD_ConditionBehaviour --
#
#   This command controls properties of conditions not defined in .cnd file.
#   The properties are : visible, draw and unassign.
#
#   GiD_ConditionBehaviour condname [property | cmd property]
#
#   cmd could be enable or disable.
#
#   examples
#
#     GiD_ConditionBehaviour Line-Constraints disable visible
#
#   when querying the properties you can provide a list of properties and
#   the result is the state for each property. The return value is a list of pairs
#   name value, like this:
#
#              {visible disable draw default unassign default}
#
#   the value "default" means that nothing has being set for this property.
#
#  Note: draw and unassign can be set or query but

Good morning

I have tested the GiD_DataBehaviour function. It is a useful function
that allows new programming possibilities.
I noticed that there exists only in the 7.5.3b GID version.

Note that the GiD_DataBehaviour function of GID 7.5.3.b can be applied
to materials and conditions but not to BOOKS. I will be very interested
to apply this functionnality to BOOKS (next beta version !?)

Thank you again.

Hi, indeed you can apply GiD_DataBehaviour  to materials book, for instance

GiD_DataBehaviour Materials Book_2 disable assign

What it is not implemented is GiD_DataBehaviour for Conditions.

Hello,
    I downloaded the post lib from URL
ftp://gid.cimne.upc.es/pub/gid/Tools/gidpost1.5.tgz . When I try to link the
example testpostfor.obj, an error appears:

testpostfor.obj : error LNK2001: unresolved external symbol
_GID_BEGINSCALARRESU <mailto:_GID_BEGINSCALARRESULT at 56> LT at 56.

I recompiles the source, the same error appear also. So can you give me a
right or a new version GiD post lib.

Thanks in advances.

Compaq Visual FORTRAN 6.6C.
But C version workes.

In the fortran file, if we comment the call line, 
      CALL GID_BEGINSCALARRESULT('Scalar'//char(0),'An.'//char(0),1.0,0,
     .NULL,NULL,NULL,NULL)       

the program will work.

So I think there is something wrong about the subroutine
GID_BEGINSCALARRESULT in lib.
Maybe the mistake is in the interface of C and Fortran.

hank you Enrique for the response but my problem is more complicate

I assign materials to several mesh elements.

1. When I use the command GiD_Info materials in a Tcl script, I obtain a

number for each material assigned.
2. When I use the *MatNum function in the .bas file, I have got other
numbers for the same materials assigned to the same entities !
3. and when I export my mesh in a GID mesh file (.msh in ASCII format) I

obtain other numbers, still different, assigned to the 3 nodes elements
(last column of the file) !!

So, I am lost because I need in my .dat file the numbers contained in
the last columns of the .msh file and these numbers should be associated

to the properties of  materials assigned (.mat). But I don't know how to

call the good function which will give me the good association
number/material. Is it possible to do that ?

Thank you again for your response.

G.W.R. Geis

...
Thr GiD-Tcl GiD_Info materials command returns the list of all current defined materials
for example: 
1- Mat A
2- Mat B
3- Mat C

If you for example only assing to your model the material B and C, and use a template .bas (*MatNum) to write the calculation file, then unused materials are ignored in the new output material numeration (tho avoid numeration jumps):
Mat A - unused
Mat B - output num= 1
Mat C - output num= 2

In other hand, if you export  a GID mesh file (.msh in ASCII format), the numeration is the initial one.
Mat B - output num= 2
Mat C - output num= 3

You can for example avoid to mix this two outpur types. Don't use "export GID mesh file", can also write the mesh from the .bas template:

Or you can also write from the .bas file auxiliarty information to identify the number with the material name (*MatProp(0))
*loop materials
   *MatNum *MatProp(0)
*end materials

Thank you Enrique,

The numeration used in the .msh file is really difficult to used,
especially if one uses differents BOOKS and if the user define several
new materials belonging to different BOOKS, so I think I gonna write the
mesh file from the .bas file. It is a good idea !

Thank you again.

Hi, GiD teams

I have a model in which two volume entities (with different material types) shared an exactly same interface surface.  I want to make them share the same nodes at their interface surface after solid meshing.  I have tried the creation of intersection or conatct, but not successful. Can someone give a suggestion and brief instructions on this problem?

Thank in advance!

You don't need contact or make interesections.
You must only create a single surface (not two copies), and select it for each volume boundary.

The geometric topology is refected in the mesh (if geometric entities are shared, then mesh entities are shared)

Hello;

I would like import a mesh created in another mesher
and use in Gid with the same geometry to asign
properties. 
I try to explain better;

I would like to try a diferent mesh in TDYN (it is
prismatic and tetrahedric elements), i created in
another mesher, so now i want to import to Gid, i
guess two methods, with gid format, or stl format, but
how gid get associate this mesh to my geometry??, or i
must put the conditions directly to the mesh using
layers??, or i would use background mesh command?

Advanced thanks
Pablo

It' not possible to import a mesh, and assign to geometric entities. In
fact, after generat a GiD mesh, mesh enties
does not mantain any link to their source geometric entities.
You must directly assign conditions over the mesh
(usually it's not easy, because you probably have a lot of elements)
Note: a "Background mesh" is an auxiliary mesh used to spatially assign mesh
sizes when remeshing.

If it's possible apply the conditions over GiD geometric entities, and
generate the mesh again with GiD.

Hello,

Remember the problem :

The condition "Point-Load" is assigned to the mesh nodes 1, 6 and 11
with different condition values (respectiveley {0.0, 1} {0.0, 1}{0.0,
4}).
One wishes obtain, from the ..bas file, the following result  written in
a ..dat file :
     Point-Load basic values:    Basic 1 - 0.0 1    Basic 2 - 0.0 4
Applied basic values:    Node 1 - Basic 1    Node 6 - Basic 1    Node 11
- Basic 2

where condition values are distinguished and the nodes assignation too.

The Tcl procedure written by Enrique Escolano is very useful (thank you
Enrique for the lesson of Tcl !).
Please, I suggest nevertheless a small correction to that procedure :

    set res [.central.s info conditions Point-Load mesh]

     proc CompareCond {a b} {
      set a0 [lrange $a 3 end]
      set b0 [lrange $b 3 end]
      if {$a0 < $b0} {
          return -1
      } elseif {$a0 > $b0} {
          return 1
      }
      return 0
     }

     set conds [lsort -command CompareCond $conds]

     set values "Point-Load basic values:
"
     set entities "Applied basic values:
"
     set ibasic 1
     set ientities 1
    # Initial data ; first to be compared
     set cprev [lindex $conds 1]
     append values "Basic $ibasic - [lrange $cprev 3 end]
"
     # Note the inversion of the ibasic and ientities incrementation
comparing to the initial procedure !
     foreach c $conds {
        if { [CompareCond $c $cprev] != 0 }  {
          incr ibasic
          append values "Basic $ibasic - [lrange $c 3 end]
"
          set cprev $c
        }
       append entities "Node [lindex $c 1] - Basic $ibasic
"
       incr ientities
    }

     return "$entities
$values"

The good ..dat data file is so obtained.

I think there is no error in the present procedure. In my problem type
this is OK.

Thank you again. The GID list is a very precious archive.

Hi Gid Team

I'm working with the 7.5.3b version on windows and this don't have any 
problem, but I downloaded this version for Linux and I followed the steps of 
the installation and didn't work, appers an error ('error de segmentación' 
'segmentation fault'). So I installed other old version I don't have any 
problem.

Kind Regards
Sebastián Callegari V.

Could you send us which the Linux distribution where you are installing GiD 
and if you are trying the dynamic or static release of GiD?

regards,

Jorge.

Hello,

I wish create a function in my problem that allows the user to check the
..dat file before running the code. The input data would be also edited
in a only readable Tcl window. Obviously there is different ways (easy
or not) to obtain that result, but these from GID are often the easiest,
so...

Studying the NASTRAN problem type I noted the function entitled
WriteCalcFileCheck.
It seems that this function could be useful for my specific need. What
do think about it ? And, could you give more infos about this special
function ?

Thank you in advance.

G.W.R. Geis

Read GiD Help about Tcl-Tk exension->Event procedures

It exists a new GiD-Tcl event procedure for this pourpose (download last GiD
beta version to use this event), with this prototype:

proc BeforeWriteCalcFileGIDProject { file } {
 ...body...
 set value ...
 return $value
}

Your problemtye can define this procedure BeforeWriteCalcFileGIDProject ,
and it will automatically called by GiD before write the calculation file.
You must return "-cancel-" to abort to write the calculation file (if you
detect some bad parameter for example)

It also exists other similar procedure AfterWriteCalcFileGIDProject to be
called just after write the calculation file (then can show this file)
proc AfterWriteCalcFileGIDProject { file error } {
 ...body...
 set value ...
 return $value
}

About how to show the file, you can read the contents of the file in a
variable, named for example msg, and use our WarnWinText procedure to show
it.
Some like this:

proc AfterWriteCalcFileGIDProject { file error } {
  set f [open $file r]
  set msg [read $f]
  close $f
  WarnWinText $mgs

  set value ""
  return $value
}

Thank you Enrique for your response,

The event procedures you send are OK in my case.

Could you, furthermore, give me a simple command to destroy directly the error
window (message : error running process) at the end of the
BeforeWriteCalcFileGIDProject procedure.

Thank you again,

G.W.R. Geis

I don't know what's the cause of the related "error running process" message.

Maybe is because my sample has a bug: instead  WarnWinText $msg  I wrote WarnWinText $mgs
Or maybe you don't have a bat file to be run.

Note: WarnWinText not stop the execution flow (is non modal), you can create your own window for your pourposes, modal if necessary.

Sorry, my message is not really clear :

To check the ..dat file before running, I use the procedure (with the
corrected variable name $msg) you wrote for the
AfterWriteCalcFileGIDProject event procedure and that is OK. Doing that
I am sure that the ..dat file is really good before be ran.

Because I don't want that the ..bat file be executed just after, I
return -cancel- at the end of AfterWriteCalcFileGIDProject. Then the
error message "error running process" appears in a tk_dialogRAM window !

Now, I would like automatically destroy that error window in a event
procedure (BeforeRunCalculation or AfterRunCalculation ?). In a
consquence it will just appears the ..dat file written in the
WarnWinText.

But now, I cannot find the name of the tk_dialogRAM error window to
destroy it.

If you have got a solution to do that, I would be (obviously)
interested.

G.W.R. Geis

P.S. Maybe it is not easy to do. If not, there is no problem because at
the moment I can check my data file thanks to your procedure. My need is

Currently I can use Problem_type_solid1 to define materials and boundary conditions for a model. Furthermore, I want to define load conditions as well in the preprocessing step. Could you suggest an easy way to do it?

A load condition nothing special, it is like other conditions.
Note: It's useful to define a "force" symbol for this condicion using 3 fields Fx,Fy,Fz to orientate it.

In other hand, the Problem_type_solid1 is not a good example, it's old. 
Download the Nastran or RamSeries problemtypes as modern samples
(download it from the menu Data->Defaults->Internet retrieve , or from our web: GiD Plus)

El insertò un modulo de Tdynlin dentro de GID para el postproceso.  

Mi pregunta es Para usar GID en el diseño de embarcaciones debo tambien conseguir Tdynlin??

Efectivamente, GiD en si mismo no incluye ningún módulo de cálculo.
Para análisis de fluídos debes descargar algún "problemtype" adicional, por ejemplo Tdyn ó TdynLin  (CFD panel code)

Puedes descargar una versión de estos problemtypes desde el menú de GiD: Data->Problemtype->Internet retrieve...
Pero correr para problemas grandes necesitarás registrar el módulo. 

En la página web de Compassis I.S. http://www.compassis.com encontrarás más información, así como

move something) on the keyboard the problem stalls.
Does anyone have the same problem?
thanks
Kind Regards

Hi GiD team,
I'm trying to use GiD 7.5.5b but I'm experiencing some problems.
I've seen you reduced the dimension of some tk windows, but, for 
example, the box for matricial properties is now so small that I see 
only half of the first row.

I think the triangular mesh on surfaces has been changed, and 
now with a structured mesh one gets the quads divided in 4 sub-
triangles, instead of 2, which keeps better symmetries. With my 
problemtype GiD often crashes on it (I mesh only surfaces around 
volumes). I tried to debug it, but I don’t know where to look. 
Strangely the problem seems to occur only when I use the 
following command in Tcl:
Meshing Generate $ProblemTypePriv(genesize)
in the routine MeschingCriteria I copied from another problemtype.
(the value of $ProblemTypePriv(genesize) is fine).

No problem with previous versions.

I have also a request for post processing: would it be possible not 
to shrink the tree of different results every time the user "applies" 
a different result?

Thanks

Hello Andrea.
About your comments of the 7.5.5b GiD beta version:

1 - I've seen you reduced the dimension of some tk windows, but, for example, the box for matricial properties is now so small that I see only half of the first row.

This is because we updated GiD to use the last available Tcl/Tk 8.4.9 version. 
It's a unexpected secondary effect ot the new Tk with this "matricial property" (only in Windows). 
We changed our scripts in order to avoid this problem. 

It is available a GiD 7.5.6b version with this correction

2 - I think the triangular mesh on surfaces has been changed, and now with a structured mesh one gets the quads divided in 4 sub- triangles, instead of 2, which keeps better symmetries. With my problemtype GiD often crashes on it (I mesh only surfaces around volumes). I tried to debug it, but I don't know where to look. Strangely the problem seems to occur only when I use the following command in Tcl:
Meshing Generate $ProblemTypePriv(genesize)
in the routine MeschingCriteria I copied from another problemtype.
(the value of $ProblemTypePriv(genesize) is fine).
No problem with previous versions.

Yes, now exists a variable SymmetricalStructuredTriangles , with possible values: 1 to create four triangles , or 0 to create two triangles.
There is detected and corrected some bug on this code, specially for the quadratic case. Next version will include this corrections.

3 - I have also a request for post processing: would it be possible not to shrink the tree of different results every time the user "applies" a different result?

We anotate this suggestion to enhance the results window.

Regards

Enrique

Hi GiD team,
I think I've found what is actually making GiD crash in 
meshing:

the modified mesher of GiD 7.5.6b cannot handle a triangular 
structured mesh with the Quadratic9 option on surfaces.

Cordially,

Andrea

Hello,

I have some problems to mesh a structure composed of 2 pependicular
NURBS surfaces in contact as shown on view1.gif.

I wish the mesh to be "continued" from a surface to the second other.
That means that there are some common nodes on the  NURBS line common to
the 2 surfaces.

But, whenever I mesh the structure I have got 2 meshes that are not in
contact (see view2.gif).

I suppose that I forget a special action to obtain one mesh.

If somebody used to mesh in this way I would be very interested by an
advice.

Thank you in advance.

The geometry topology is reflected in the mesh topology.
Your surfaces are unconnected (don't share any boundary line), then the
nodes are not shared.

You must split the bottom surface with the line (menu:
Geometry->Edit->Divide->Surface->Split)
but the end points of the splitting line/s must be connected with the
surface to split !!

Before use it, can intersect all lines (menu:
Geometry->Create->Intersection->Multiple lines)

Hello

I can't see the pictures of your problem, but I think I understod what
this is about.

I had problems with structured contact elements in 3-D.Two months ago I
wrote an e-mail to this forum for this kind of elements and Escolano
told me the best version is the 7.5.3b and the most new versions too.

This is my solution:  

First: In the corner where the 2 surfaces are in contact, each surface
must have his own line, that means, two equals lines one above the
other, each one with their own points.

Second: geometry --> create --> contact --> surfaces (Pick the 2 lines) 
	  ESC

Third: Generate your mesh

I did a little example of this to help you and worked very well.If your
problem continues or if you didn't understand something of my bad
english, write me and I can send it to you by e-mail.

Hi GiD team,
I'm using GiD 7.5.6b and I noticed a problem with the result 
labels. I have some models with geometrical dimensions in 
the range of 10e6 and when I try to display results on the 
nodes in post processing the labels get funny and some 
triangles cover the whole model.
In version 7.4.9b the problem is present, whereas in the 
release version 7.2 everything looks fine.

Kind Regards

Andrea

Thanks, corrected in the new gid 7.5.8b version

I am trying to build a geometry of irregular regions in a cube.

I am using a batch file. In the commands listed for volume generation I get messages like "line number 89 is 1 times into volume generation". There are quite a few of these...

I am not sure what the problem is and I can send the batchfile to anyone who likes to look at it and let me know what the problem is...

Thanks very much in advance.

Hello Aman.
The problem is that the selected entities it doesn't topologically close a
volume.
Probably it exists some gap (duplicated lines, etc).
Can Use: Utilities->Draw higherentities->Lines  to show this gap

To bound a volume, all lines must have the higherentity value=2 (the line
must be boundary of two surfaces)

If yourself can't solve the problem then send to me your batch file, to test
it.

Hi GiD's Team,
I've started working with GiD as a postprocessor utility and I'm having
some problems when loading hexahedra type elements. Though the archive
seems to be formatted exactly the same as the one on GiD's Manual ('Mesh
Example' and 'Results Example'), it keeps setting an error message
"incorrect element number" pointing to the line where it lies on "End
Values".
I've tried two types of hexahedra elements (8-node and 20-node). The
20-node one has worked properly. The 8-node one hasn't.
Could anyone send me a simple example where hexahedra type elements are
loaded in post-processing operations?
Thanks.

Yourself can write a preprocess mesh in GiD ASCII format, with
Files->Export->GiD Mesh..

This is a mesh example with eight hexahedras of 8 nodes.

Is it possible to pick an arbitrary point in a 3D model to do a
point-analysis. I can not make it work. I can only do point-analyses at
nodes in my 3D model.

With nodal-results, it is possible to select an existent node, or also another 3D coordinate (interpolating results).

Note: The <control-a> key swap between "join" and "nojoin" selection mode.
in "join" mode must pick a node or enter his identifier number, in "nojoin" mode must enter the coordinates x y (and z if is not zero).

Hello.

In order to create a semi-structured mesh, must set for example
Meshing->Structured Volumes
Then Select the volume and ONLY assign a number of structured devisions for the lines in the "extrusion" direction.

Then, in general, GiD can automatically detect that must generate a semi-structured mesh of prismas like this.

(if you assigned structured divisions to other lines, can restore the void default values with Meshing->MeshCriteria->Default->Lines)

You can also assign  unstructured sizes to the master and/or slave surfaces in the other direction, or set the element type of this surfaces to triangle for ambiguous cases.

Note: this feature is only available in the last 7.5.8b beta version (now only for Windows)

Hello,

I would like to know how a 3D surface can be represented using GID
For exemple the surface of a river.

Thank you

Abdou

You can create NURBS surfaces with several methods:
menu: Geometry->Create->Nurbs surface

- By contour, create the surface interpolating the selected boundary lines
- By a family "near-parallel" lines
- By Points/By line points, selecting a cloud of points (the surface will be
untrimmed, and not interpolate this points, only approximate them)

Other useful method is create from the copy window, by extruding some source
lines (by translation, rotation, sweep,...)

Other non-useful methods is:

Thank you so much Enrique but sorry,

my question was not explicit enough. I am simulating some kind of inundation
or dambreak. The preprocessing (mesh) is ok with GID , but at the
postprocessing step, I can only visualise the z-movement of the surface of
water using colors, View results-> Contour Fill for exemple. Whereas I
want
a 3D animation.

If these explanation is not enough, please look at

Your solver must write a vector results with the nodes displacements in each
time step, and you can use this result to show the deformed mesh.

Open the View results window (menu: Window->View results)
And in the "main mesh", select "Deformed", and select the vector result to
use for the deformation. This vector can be a relative increment to add to
the original mesh, or the final position vector (must check "position
vector")
Also can set the "factor scale"

Can see an animation of all steps from the Animate window (menu:
Windows->Animate), this film can be saved as mpg, avi or animated gif

Hi,
I would like to ask a couple of question about the possibility of 
performing a surface reconstruction in GiD (version 7, from 7.2 to 
latest beta) starting from a surface mesh.
I know that GiD is not a reverse engineering tool, but I cannot afford 
the expense of a tool like Geomagic or Paraform.

I'm experimenting with the following procedure.

1. Create a surfmesh geometry by a combination of "Create Surfmesh" 
commands in combination with "Select by tolerance" and "Tolangle = x".

2. Clean the surfmesh entities, tweak the line entities and create 
4-sided nonplanar nurbs surfaces. At this point the topology in GiD is 
correct (no cracks/gaps between contiguous surfaces)

3. Export the resulting model in IGES format.

The issues I am experiencing are of bad surface tolerance (when I import 
the IGES in other programs, I must set the import tolerance value at a 
very high level).

My question is: are there any documented/undocumented methods in GiD to 
check the NURBS quality? I can try to edit the nurbs, raise their degree 
and reparametrize them, but I have no control on how this affects the 
geometrical gap between the nurbs. Additionally, based on your
experience, how would you rate GiD's ability to export the geometry in 
IGES format?

Moreover, does the "Import tolerance" value affect the geometry 
created/modified in GiD, and exported from it? If yes, how?

I repeat: I know that this is not GiD's playfield, and I am really 
astonished by what GiD is able to do with the SurfMesh command 
(expecially compared to more expensive alternatives).

Thanks in advance for any possible answer,

Arturo di Gioia

...
Sorry, but there not exists any tool to enhance the precision of a surface
(to decrease the gap distance between the surface and the trimming lines
"over" this surface).

But maybe you can try some tools before create this surfaces, to enhance his
boundary lines.
For  example:
0- Create surfmeshes and delete it to have only curves as you related
1- Convert all types lines to NUBS lines (because other tools only works for
NURBS lines)
     menu: Geometry->Edit>Convert to NURBS->Lines
2- Force some "near tangent" curves to be tangents
    command: Geometry Edit TangentNurbsL
   (not exists a menu entry for this command, must use the rigth buttons or
write in the lower command line)
3- Collapse entities to remove points between tangent lines, and avoid too
small lines
     menu: Utilities>Collapse->Modes
  (check the value of the ImportTolerance, in the  preferences window,
points close that this tolerance will be join)
5- Simplify lines, creating another approximated interpolation (can create
better surfaces after)
    menu: Geometry->Edit>Simplify NURBS->Lines
6 -Then create surfaces by boundary. An iteresting option is to use
"Automatic" to search surfaces with "n" sides
     menu: Geometry->Create>NURBS Surface->Automatic
7 - Complete manually the model adding or deleting surfaces, and export it

Note: Import tolerance is used when importing IGES, to join separated
entities, but not when exporting IGES

If you created also volumes, can try to select "B-Rep output style" in
preferences, to write also the topological relations between geometrical
entities, but some CAD's doesn't support this boundary-representation style.

Dear GiD-Team,

I am wondering, if there is any possiblity to get a finite-element mesh of
the following geometry:
I have one cylinder with radius 3m on whose top is another with radius 2m
which has a cylindrical hole (coaxial), which has the radius 1m, see the
attached picutre. My problem is that I cannot generate a mesh at the
touching interface of the big cylinder and the cylinder with the hole that
uses the same nodes for both surface meshes. I am using GiD 7.5.8b
professional version. Thanks a lot in advance for any help.

You must split the top (radius 3) surface, to create 3 parts: two rings and
a circle
menu: Geometry->Edit->Divide->Surfaces->Split
and select the surface, and the lines to split in two parts

The middle ring must be shared between the two volumes (must delete a
duplicated)
(for example wiht Utilities->Collapse->Model)
or delete this common surface to create a single volume.

all orientated along positive z-direction and each in an own layer. Then I
created the cylinder with the hole by the volume boolean operation substract
(cyl2 - cyl3) and sent the inner surface of the resulting cylinder with hole
which was still in the layer of cylinder 3 to the layer of cylinder 2.
Trying what you told me in your last mail with that geometry did not work,
as the top surface of cyl1 disappeared after splitting it. However, if I
tried to generate a mesh with this geometry, the error
"19   Check self intersections, or bad oriented boundary"
was reported by GiD.

May it be that I do anything wrong during the geometry modelling?

Thank you for your help,

yours sincerely,

I repeated your creation mode and it worked ok. (with a split of the circle
in three parts, and a collapse to join the midpart)

Maybe the problem while splitting the surface is a corrected bug of your GiD
version (use help->About to see your version).
Try to download the last available beta version 7.5.8b (the password is the
same for all 7.x versions)
http://www.gidhome.com/download/do07.subst

Also are possible other options, instead to use split , for example:
a ) For planar shapes, as your case, can delete the surface and create two
new surfaces selecting his boundary (and hole) lines
b) For non planar shapes it is not sufficient the boundary to reconstruct
the same internal shape, but can create a new surface trimming this shape
    Geometry->Create->Nurbs surface->Trimmed
    select the surface to get his shape, and the trimmed boundary (and
hole/s) lines.
    Then can delete the old surface

Note: in general is not recommended to use GiD boolean operations, it can be
slow and unstable. For example in your case it is possible to create a
planar ring, and create the cylinder ring volume by extrusion with a
translacion transform (from the copy window)

I had a question the other day about doing point analysis in a 3D model. I
still have problems with choosing an arbitrary point. When I have a
hexahedra mesh there are no problems, I can choose any point in space. Now I
want to have tetrahedron elements and then I can not choose any point I
want. I am forced to choose nodes. I have tried both in GID 7.2 and in ver
7.5.8b on Windows XP.

It seems that there is some problem when plotting "point analysis" at interpolated points with tetrahedras and nodal results.
It appears a message like "the point lies outside the sets", also if the point is inside!!.

It will be corrected for the next beta.

You don't need to use the GiD boolean operations (as I related in a previous mail actually they are very expensives and unstables).
It is only necessary to use boolean operarions if it is needed to build the surface's intersections.

You must create the out cylinder volume, and then create a hole in this volume
menu: Geometry->Create->Volume->Hole
and select other internal volume/s to substract (this operation not create intersections)
Note: This internal volume/s is deleted, maybe you need to create it again, to fill the hole with another volume

When creating a volume you select the outer and inner boundaries. Automatically are detected inner boundaries as holes of the outer boundaries.
(intersections are not checked)

Hi everyone,
I'm working with GiD 7.5.8b and I noticed that if you have a 
hollow surface made of the subtraction of two quadrilaterals 
(mine have parallel sides) and you assign the element to be a 
quadrilateral, if you go for a structured mesh of the surface, 
as soon as you try to assign number of elements on the sides 
GiD crashes.

With other shapes it seems not to happen. May be is 
something in the search of opposite sides in the structured 
mesh algorithm?

Kind Regards

Andrea

Hello Andrea.

We tried to repeat this bug several times, but it worked ok
(not crashed, only showed a message like: "Problems in surface 1. Marked as
structured and it cannot be".)

Can you send a model with this problem (or more detailed instructions to
repeat it)?

Subject: [GiDlist] Meshing crash

> Hi everyone,
...
Hello!
 I am trying to view the results of another program at the postprocessing 
section of GiD.
 There are 2 meshes: one with triangular elements that is a membrane and one 
with linear
 elements that are the cables around the membrane.
 The original file generated with both meshes and results is "results". And 
I don´t understand why when I choose to view "cable load" results there are 
some triangular elements appearing at the corner, as you can see on the 
image attached.
 Just to test, I manually erased all the results ("modresults") and 
conectivities that had to do with the membrane and left only the information 
about the cable and then it works, on "cable load" you see only linear 
elements!
 But I need both in the same file, so can anyone tell me what is wrong with 
the file or if is there any parameter that I can change to make the original 
file "results" work???
 Thank you very much!!!
Cristina.
  Cristina Almeida Bueno e Silva

Hi,

that's because the nodes are shared among the line elements and the triangles.
As the three nodes of the triangles at the corners are the same as the ones of
the line element and as the result 'cable load' is defined for those nodes, the
triangles are drawn. 

One solution, the easiest, would be to renumber then nodes of the line
elements. Another one would be to remesh the triangles so that there will be
two triangles per corner, but this is quite more complicated.

Another way is to shut off the triangle mesh, just by open the window
Windows->view style, select the 'S deformed' line on the listbox and clicking
the '( )' icon to switch it off. Perhaps is this what you wanted?

Hello GiD team!
I tried it now as well and the criteria for the crash (which 
actually happens sometimes) are not clear to me.
It happens with triangles as well, and normally after you 
have been playing for a while with the meshing, therefore is 
quite difficult to imagine what could be causing it.

I send you the model I was playing with and a picture of the 
crash ...

Probably you need to create the intersection of "touching" surfaces, but I don't know what is exactly your case.
Send us your model compressed as zip file to check it.

Hello,

i have checked the behaviour of GiD with the following Versions

GiD 7.4.3b
GiD 7.5.8b

on Windows 2000 SP4 and Windows XP SP2, both german versions.

Are there any variables that are set differently in the linux and
the windows version concerning tolerances.

Since the created structure is much thinner than the diameter of the cylinder, there
could be problems with point creation tolerances, that match points on other points
and therefore can not extrude the surface correctly.

But that's just a guess.

Do you have any other hints where to find the problem.

I've been testing this behaviour on four different machines.

Regards Martin

From: "Enrique Escolano" <...
The default values are the same in windows as in Linux.
Could be the tolerances, but i don't belive it, because as you said that the
cylinder with 5e-4 height was created o.k. but not the one with height 5e-3  . 
That is what is strange.

In a clean Windows XP SP2 actualized and with the german regional
configuration, i installed and started GiD, and tried the commands and worked,
both cylinders.

Althought the tolerance can be set at 'utilities->preferences->import', it does
not affect the creation of the cylinder.

Try deleting the gid preferences located in the gid.ini file inside a directory
like:

C:Documents and SettingsYOUR_USER_NAMEProgram DataGiD
(well the german translation of program data --- Programdaten?)

In our tests it worked always well.

A detail, instead to use nojoin, can use Fnojoin (to force nojoin, without 'unexpected command error' if the current mode is already nojoin)
escape escape escape escape geometry create object cylinder Fnojoin 0,0,0 0.0,0.0,1.0 12.5e-3 5e-3

In other hand, we changed GiD for the next beta version, to avoid to show the "enter normal" window and other popup windows if the user provided the answer, as your case.
then it is not necessary to disable windows (and after enable it again) with your command:
utilities variables UseMoreWindows 0 escape escape

It is a corrected bug of the 7.2 version. Download a new beta version, like
the 7.5.8b

Note: Can use the program md5.exe in order to check the integrity of the

for example, for the Windows version, open a command window, and write

If you obtain a code different of :  8ed8b9a6f1fba31e11e5c3de47d4e47b

With border graph I am only able to display graphs of data which is

This has not been possible with all versions of GiD that I've tried, it
seems such a basic necessity and in most other post processors you define a

Hello,
It is not a licence problem or limitation of an academic version.
It seems than you can not execute the solver, and then it not exists any
result file (*.flavia.res) to postprocess.

The cmas2D sample problemtype include only an 'analysis' program: cmas2d.exe
compiled for Windows platform.
If you are using other platform need to recompile the included source file:

Hi there,

I have been using GID to generate triangular finite element grids for a while, I was using the 7 version to do so but on a month trial password basis, now I run out of those passwords so I renovated my company's 6 version to install it on my computer, because they had it on an old computer...anyway, I am having problems creating grids, because the program just chooses a really small element size despite the fact that I enter a different size before generating the new mesh.

I have tried with several of my old projects/grids, that I generated with the 7 version and some of them I can generate the mesh again with the pro 6 version and some of them just keep on changing the elements size automatically to something really small, say from 3 m to 0.5 m thus creating a mesh with a million nodes, when I usually run my models on 50,000 node grids...

So basically my question is, why does the GID 6.1.2 change the size of identities automatically when I hit the "generate" mesh button?? why does it do that with some projects and not with others when these projects are pretty much similar or identical?? Is there any way to avoid this??

Thanks very much for your time and help

Dear Sir,

Two GiD versions always have some difference, and you must not expect to obtain the same mesh with two different versions.

By default, both versions (6.1.2 and 7.x) try to correct the user assigned mesh sizes (else must be not possible to generate the mesh)

Can deactivate this automatic correction from: Utilities->Preferences  - Meshing - Automatic correct sizes
But if you deactivate this option, you are responsible to manually assign more coherent sizes to geometric entities, in order to obtain a mesh.

Check also other meshing parameters values, like the element sizes transition factor.

Do you have any suggestion?
(one solution is to mirror the lines only and define the 
surface however sometimes this can be time - consuming)

Hi,

You must swap the surface normal: the elements will have the same orientation as the source surface

GiD has some tools about normals: Utilities->DrawNormals->Surfaces
Then select the surfaces, and the normal vector will be drawn.
When drawing surfaces, the contextual menu (click right mouse button) has more contextual options:
-All swapped (change all selection)
-Swap some (change only some selected)
-Swap group (made all selection to be coherent between neighbour elements)
-Sel by normal (select by a direction)
-Color (draw surfaces filled by color: back faces in yellow and front faces in its layer color)

Can use Swap some and select the surface/s to change its orientation to the opposite normal.

Hello everyone,
I was wandering which is the effect of the command:

-Sel by normal (select by a direction)

in the normal menu once the normal are displayed.

A wish:
For BEM and other applications the orientation of surface and line 
normals is fundamental, and it is almost always necessary to control 
and reorient them in a model. It would be than definitely handy to 
have a dialog window (similar to the layer one) opening at the 
command "Draw Normals", where the user could manage the 
normals and have always the result displayed without needing to re-
issue the command "Draw Normals" again.
I hope this suggestion could be useful for the GiD interface 
development.

Best regards

Hello Andrea.
You are right, control of normals is interesting, and the current mode to use this tools is old and not very intuitive.
It must be enhanced adding some window or better menus.

Sel by normal  is interesting for example, if you have a shape that can be projected in a direction (useful in sheet forming, etc)
to select only the entities with normal pointing approximately an user direction (in fact all with positive dot-product)

For example, if you have this surfaces in the ZY plane, you can swap only the surfaces with normal pointing to -Z axis (0,0,-1)

use: Utilities->Draw normals->Surfaces
then you select all surfaces (elements in mesh view)
and you filter this selection with
SelByNormal and enter a direction, for example: 0 0 -1
then only the entities with normal pointing in the same half-space of this direction remain selected
and you can use AllSwapped to swap the orientation of the yellow surfaces

Best wishes

Enrique

Thank you Enrique!
In cases with many surfaces or elements the command is very 
handy.

In BEM, as you know, the most important information about 
normals is their ORIENTATION in relation to the geometrical 
entities of which their support is the boundary, like:
- (2D) line normals: oriented outwards or inwards with respect to 
surface/s "owing" them?
- (3D) surface normals: oriented outwards or inwards with respect 
to the volume/s "owing" them?

Three years ago I programmed something which allows extracting 
this critical information from the GiD VOLUME properties, but only 
provided the user uses some precautions (it makes use of the info 
DIFF1ST and SAME1ST). It works but is not as automatic as it 
could.

When creating a single Volume from a series of surfaces GiD 
reorients them in order to point inwards, therefore I guess it 
makes use of the information I was mentioning. But than, with the 
presence of other volumes sharing some surfaces with the first 
one, part of the information is “lost” or anyway becomes no more 
retrievable. From the VOLUME list it is in fact possible to know only 
the RELATIVE orientation of surfaces with respect to other surfaces 
around a volume, but not their ABSOLUTE orientation with respect 
to every single volume they are part of.
I don't know if my "analysis" makes any sense in the scheme GiD 
uses for these things. If it does, do you think in some future GiD 
betas or releases it will be possible to have access to this 
information, so critical for some applications?

Sorry for the boring and long mail.

Best regards,
Andrea

Like BEM, GiD also needs to know what is inside and what is outside to generate the mesh.

A volume has a list of surfaces and their senses: 
If the surface normal points inside, its sense must be SAME1ST, else must be DIFF1ST
(usually when you create a volume the surface normals are swapped in order to have all SAME1ST, but if the surface is shared by two volumes
it must be SAME1ST for one volume and DIFF1ST for the other)

Do you have access to this information from Tcl with the command GiD_Info list_entities volumes <id_number>

The surfaces also have a similar topology, its lines are oriented: a SAME1ST line has the surface interior turning to the left 

What information do you need that it is unavailable now?

Hello Enrique,
thanks for the answer and the explanation.

I think I eventually understood how it works: if a surface is 
labelled as SAME1ST its normal is ALWAYS pointing inward, 
no matter how the volumes have been generated, otherwise 
it is pointing outward. All info is then provided and there isn't 
any missing bit. Sorry for having been fussy about this.

I was getting the info regarding SAME1ST and DIFF1ST from 
the Tcl command:
[.central.s info list_entities volumes 1:[NumVolumes]]

Hi, GiD teams

I have a surface triangle mesh generated by myself. I want to be able to use GiD to convert it to IGES format. The import of the model into GiD is fine, but when the model is exported as an iges file,  the file is almost empty in that there is no geometry information or others. The attachment is a testing example. Any suggestion on this?

Thank you

The mesh triangles are not written in the IGES file, mainly this is a geometric format.
Can convert each triangle to a geometric surface:
1- Export your triangles with the auxiliary template DXFSAP2000 
    menu:  Files->Export->Using template (only mesh)->DXFSAP2000
2- Import again in GiD this dxf file. You will have a surface by triangle

Hi, GiD teams

Following the steps you suggested as below, I am able to convert a surface triangle mesh (generated  by another lcoal programme) to .iges file format. The problem is that the corresponding .iges file contains only point coordinates and line definitions without surface element definitions. So this file can't be used for 3-D mesh generation. Any suggestion on this problem?

The attachment is the test model and its corresponding .iges file.

thanks

The surfaces of your test.gid model were not written in the IGES file because they are 'surfmesh' entities.
A 'surfmesh' is a GiD pseudo-surface (with a mesh to define the internal shape). This entity cannot be translated to any IGES entity, then only the curves and points are written.

Don't import the triangle mesh with Import->Surface mesh (it create 'surfmesh' entities)
You can use my related trick:
0- Read your GiD ASCII mesh with
    menu: Files->Import->GiD mesh
1- Export your triangles with the auxiliary template DXFSAP2000 
    menu:  Files->Export->Using template (only mesh)->DXFSAP2000
2- Import again in GiD this dxf file. You will have a surface by triangle

Hello GiD team,
I was wondering if it is possible to create a geometrical  
Object like a cylinder in Tcl (.central.s process  geometry 
create Object Cylinder), avoiding creating lines, surfaces and 
volumes separately. I tried and GiD was complaining because 
it would use a dialog window for user input.

Hello Andrea,

yes it is possible.

At first you have to disable the dialog box by using:

>> .central.s process Utilities variables UseMoreWindows 0

Then you create the cylinder by using

>> .central.s process Geometry create object cylinder Fnojoin $center $normvec
$radius $height

where $center 	center of the cylinder x,y,z
      $normvec  direction of the normal of the bottom surface x,y,z
      $radius   radius of the cylinder r
      $height   height of the cylinder h

Fnojoin forces GiD to create a new point. Therefore you have to
collapse your model if there has already been a point at this destination

Hello everyone,

in order to be able to reset the previous option of 
"UseMoreWindows" I need to store the standard variable 
value the user is working with. Therefore I guess I should 
access the global variable ChangeVarInfo(UseMoreWindows). 
But even if the variable is changed to 0 or no, the behaviour 
of GiD remains unchanged and windows are used to interact 
with the user. I tried the following two expressions:

global ChangeVarInfo
set ChangeVarInfo(UseMoreWindows) 0

global ChangeVarInfo
set ChangeVarInfo(UseMoreWindows) no

This on the contrary works:

.central.s process Utilities variables UseMoreWindows 0

Which is the difference between the three expressions?

Thanks

Best Regards

Andrea

...
Hello Andrea,

while greping the gid/scripts directory for

>> ChangeVarInfo(...)

i found only entries that had the Name

>> set ChangeVarInfo(Usemorewindows) yes | no | beginner

maybe that's the solution, if the switch/case statement is case-sensitive.

You can even use

>> central.s disable windows 'value'
>> The value 0/1 Enable/Disable Windows (GiD displays, or not, windows which require
>> interaction with the user)
>>
>> EXAMPLE to disable the interaction windows:
>>

>> .central.s disable windows 1
...
Hello Andrea & Martin,

To avoid to open popup windows, must set the GiD variable UseMoreWindows to 0
with
.central.s process Utilities variables UseMoreWindows 0
or 
GiD_Process Utilities variables UseMoreWindows 0 
(they are similar, but I recommend you to use GiD_Process)

This command change an internal variable (of the C/C++ kernel)

ChangeVarInfo(UseMoreWindows) is a Tcl/Tk global variable used to temporary store the value of UseMoreWindows.
When you open the preferences window, ChangeVarInfo(UseMoreWindows) is set to the internal value, and when you press the Accept button the internal value is set to the current ChangeVarInfo(UseMoreWindows) value.

For your problemtype, can use your own Tcl global variable to store the previous state, for example:

#save the current value and set a new value
global BeasyPriv
set BeasyPriv(UseMoreWindows) [GiD_Info variables UseMoreWindows]
GiD_Process Utilities variables UseMoreWindows 0
...
#restore the old value
global BeasyPriv
GiD_Process Utilities variables UseMoreWindows $BeasyPriv(UseMoreWindows)

Valid UseMoreWindows values are: Create new point: 0==always 1==ask  -2==never

Usually, if you provide to GiD the answer in the same line, then the user won't be asked, and then it's not necessary to deactivate windows.

Can also use this Tcl commands to temporary deactivate redraws, and messages:
GidUtils::DisableGraphics
GidUtils::EnableGraphics

Asunto: [GiDlist] How to remove "afterimages"

Hi,

I'm a Professional Gid user.

I recieved a solution file to remove "afterimage(or overlapped images, see the
attached file)", which come out whenever I click a menu on Gid screen, from Gid
support division.

After installing the file provided by Gid support, I changed the language and
nationality options from Korean to English(US), so that I could some of
afterimages. But I could not remove them compleletely yet.

So, I would like to know how to run Gid without afterimages when I run it.
Please let me know it and remove them.

Thank you,

What you call meshes are, in fact, surfaces of your model. And from the
PowerPoint you've sent, i guess that you have scaled your model but, instead of
using the 'Utilities->Move' window, you used the 'Utilities->Copy' window, and
so the model is copied from the original position to the final one. Try scaling
the model with the 'utilities->move' window. If i'm wrong ¿can you explain me
the whole process you followed to get this picture? ¿which version of gid are
you using (Help->About)?

If you have experienced more graphical problems with GiD, ¿which graphic card
are you using? try downloading and installing the latest driver for your card.
if the problem persists try to start GiD in safe mode (from the 'start menu')
and activate 'use Software OpenGL'. If the problem persists, try to deactivate
the graphic hardware acceleration (Control Panel->Screen properties->Advanced
options). Also try a different colour resolutions (select 32 bits of colour for
example).

Hi GiD team,
I have been trying to use GiD 7.5.8b for creating animations of a 
simple model and I experienced some problems.
I would like to render a simple volume with few other surfaces. The 
target is having transparent surfaces with visible lines. I tried with 
a single window and I couldn't do it because of bad rendering. The 
rendering was ok only with invisible lines. By chance I selected two 
windows and the second appeared to be fine. The picture attached 
to this e-mail regards the situation with two windows, the 
rendering on the right is ok.
The same situation repeats over different Windows machines and 
the second window is always fine at the beginning. The same is 
valid for the GiD release 7.2. Linux machines seem not to have any 
problems.
Playing around with the rendering of the second window can cause 
it to have the same problem of the first.
Trying to animate the second window with a rotation and recording 
to a gif file causes GiD to crash and in some cases different errors 
arise.
On both Windows machines the graphic card hardware acceleration 
is set to 0.
Thanks for any suggestions.

In the Automatic animation list is it possible to delete an animation 
only with right-click-Delete?

Best regards
Andrea

Hi,

I am postprocessing some results using GID. I usually load up an image as background and then read results from the .bon .res files using:
"utilities backgroundimg realsizeimg"

By doing so, the grid results overlap the image loaded as background. My question is, is there anyway for blanking part of the grids results with some image or file?? as can be done in surfer for example. I have a grid in which some of the nodes should be covered up or blanked in the final image before creating and image out of it...I guess I could try to do so with surfer but I would like to know if this can be done in GID so I only work with GID, plus I could create a batch file to speed things up.

Thanks a lot.

GiD 7.5.8b OS win2000 SP4

Hi
I have a custom application which adds & removes menuitems via a .tcl file
e.g.
CreateMenu "Process" "PREPOST"
InsertMenuOption "Process" "Flight" 0 "run_1 { $dir }" "PREPOST"
RemoveMenuOption "Help" "Tutorials" "PREPOST"
RemoveMenuOption "Help" "What is new" "PREPOST"
etc...........

When I select this problem type, the menu bar customizes correctly but if I
use undo  any time later after performing some actions I get GiD warnings
i.e. Menu ERROR:Option menu Tutorials doesn't exist in the preprocess , Menu
ERROR:Option menu What is new doesn't exist in the preprocess ...etc etc
depending on what menuoptions I have removed, it doesn't seem to stop the
undo but is an unwelcome feature :-(
As well as this I get a phantom extra menu item which is a copy of my
Process button without any sub options.
Is there any way to prevent this unwelcome behaviour? The custom application
worked perfectly on GiD 6.3.0b & win2000 ?

thanks in advance

Hi Andrea,

you seem to have the same problem as i did.

If creating too small geometries GiD has problems in handling these,
starting from within the geometry generation and reaching up to the
creation of the mesh.

As a workaround just create a scaled model with factor 100 or more.
Another workaround is creating a point with in the gravity center of the
model and scaling the model by factor 100 or more.

After doing this the mesh generation worked.

Bye Martin

Thanks Martin,
unfortunately changing the units in this model is not that 
"easy" because is for a sort of benchmark for crack 
propagation ...
I managed to have the mesh from GiD 7.2; I believe that 
version of the mesher is not so scale sensitive.

Hi Andrea and Martin,

I'm Abel Coll (a GiD developer). With the last version of GiD (that is not
available yet) this problem is solved.
Mesh can be reached without any problem, as you see in the attached image.
GiD crashes in version 7.5.8b for some bug that have been corrected
recently.
It's not necessary to scale the model. Maybe this week (or at last next
week) will be available next beta version, with this problem solved.

Is there a geometric procedure like "round" where one specifies a radius
then selects the edges of the solid you wish to modify to blend one surface
into another with the specified radius? or "chamfer/bevel" an edge at a
specified angle?

for lines there is the arc tangent command, but I can not see the 2D/3D
analogy.

Hi,

You have this option in the RightButtons menu. Yo acces to it by
Geometry->Create->BlendSurfs. You must specify the radius of the "arc
surface" and the edge you want to "chamfer" (it must be shared by 2
surfaces). This command isn't still working 100% well, so it is in the
RightButtons menu. Probably in the next beta version it will be checked and
placed in normal menus.

Hi GiD team,
I'm using version 7.5.8b and I have three minor problems:

1 If I change the problemtype the materials submenu and 
some other under "Data" tend to disappear. Note that in the 
"Right Buttons" toolbar all the "Data" submenus keep being 
there.
2 Drawing the materials with colours changes the background 
colour.
3 If I use "Create Object" the snapping is not working, 
whereas with lines and points everything is fine. (It seems 
the grid button at the right bottom has no ToolTip assigned).

I hope these info can help you improving GiD.

(1) Once the triangulated surface has been read into GID, is there a way to 
manipulate it
so as to come up with a smooth surface using nurbs?

(2) Let's say I generate 2 separate volumes from 2 different triangulated
surfaces. I experience problems when trying to subtract one volume from the
other one. I receive an error message saying 'Not Close Volume'.
Can you help me? I am including a simpler example of my problem
which involves the subraction of 2 cylinders generated from triangulated
surfaces.

(3) I am working with large meshes and find GID slow on a PC
(Pentium M Processor 725 (1.60 GHz/400MHz FSB),512 MB Ram).
Do you think that the Linux/Unix version would run
much faster on similar computer configuration, or is it that my PC is simply
slow and I need to upgrade both CPU speed and RAM)

Thanks.

Dear sir,
About your questions
(1) Once the triangulated surface has been read into GID, is there a way to  manipulate it so as to come up with a smooth surface using nurbs?
Dxf is a very bad graphics exchange format, it don't support NURBS surfaces, then smoot surfaces are translated as a collection of triangles, and it's not possible to recover the original smooth shape. For a simple geometry, like yout two cylinders, it's better to reconstruct them in GiD (by revolution, etc), using the imported geometry only to get some dimensions.

Check if your external CAD can export in other better formats, like IGES, Parasolid, ACIS or VDA

(2) Let's say I generate 2 separate volumes from 2 different triangulated surfaces. I experience problems when trying to subtract one volume from the other one. I receive an error message saying 'Not Close Volume'. Can you help me? I am including a simpler example of my problem which involves the subraction of 2 cylinders generated from triangulated surfaces.

Boolean volume operations currently are slow and unstables in GiD. 
They are slow because it's necessary to calculate all the intersections between lines-surface, and surfaces-surfaces. It works better with few smooth surfaces instead a lot of small triangles. After calculate intersections, and split entities, sometimes it's not possible to close a volume, and it's necessary manually solve some problem (some failed intersection, etc). This features must be enhanced for future GiD versions.

3) I am working with large meshes and find GID slow on a PC (Pentium M Processor 725 (1.60 GHz/400MHz FSB),512 MB Ram).
 Do you think that the Linux/Unix version would run much faster on similar computer configuration, or is it that my PC is simply slow and I need to upgrade both CPU speed and RAM)

The Linux/Unix versions run at similar speed that Windows versions.

I don't know any program capable to automatically convert this
triangulations to several smooth surfaces.
I tried some specialized reverse engineering programs, like Delcam CopyCAD,
or Cadmus fashion,
but they can't automatically do this work. (in other hand, I'm not an expert
using this related programs)

Maybe you can send me some real sample (can send directly to
escolano at cimne.upc.es) , in order to enhance
GiD for this type of models.

Hi,

If I want to present the vector of the nodal displacements but the mesh is too dense (thus the picture is not clear)
I would like to present the vector only of some nodes i.e. in a neighbourhood of 
10 nodes to show one vector. Is this possible?

Hello,

By now this is not possible, sorry. But we're thinking about adding it to
GiD soon. I'm thinking of something like the amount (%) of vectors to be
drawn when the element is too small (for instance less than 10 pixels or
so.).

Hi Bahong,

This may or may not help. A colleague wanted to reconstruct point cloud
data of part of a human foot (a heel pad if I remember correctly). He
used a package called Rhino (http://www.rhino3d.com/) to "drape"
surfaces over the point cloud. He then got the surfaces into the ansys
mesher, I'm assuming via IGES. There is a demo version of Rhino
available, so maybe you could give that a try to create your smooth
NURBS surfaces before import into GiD.

Hi there,

i try to build an arbitrary shaped volume, and then to generate a hexahedron 
mesh within. But if i build e.g. the gear from the tutorial, and then assign 
hexahedron elements to the resulting volume, GiD throws an error when i try 
to generate the hexahedron mesh as follows:
Non-Structured volumes can only be tetrahedra or only points. 

How can i define the volume as a structured volume? Where is the difference 
between structured and unstructured? I did not found anything about 
structured volumes at the help-file. 

Best regards from germany,
Timo Hambürger

Hi,
An structrured volume must have exactly 6 faces (topologically is like a
cube).
In order to generate the structured hexahedrals mesh, it's necessary to
manually edit the geometry to divide the volume in parts with 6-faces. Then
you assign the number of division in the three directions.

The last beta versions have a new feature: semi-structured meshes. It
generate triangular prisms. with unstructured triangle faces in two opposite
surfaces, and an structured number of divisions in the extrusion direction.

Hello,

This mail is for add some extra information at the mail sent by Enrique to
the GiDlist in relation to the hexaedral meshes.
Using semistructured meshes it's another way to obtain hexahedral meshes.

As you will see, a volume can be meshed with semi-structured mesh if it's a
prismatic volume, where it can be distinguished to top surfaces (master and
slave), and the lateral ones. Lateral surfaces will be meshed with
structured mesh, and top ones can be meshed with any kind of mesh.
Depending on the element types assigned to the volume surfaces, result mesh
will have prism, tetrahedra or hexahedra elements.

The way of choosing the kind of mesh you want (since last beta versions) is
in "Mesh" menú, setting UNSTRUCTURED, STRUCTURED or SEMISTRUCTURED option,
and selecting the geometrical entities you want to mesh.

Regards

Abel Coll

Hi,

I  would like to include geometrical property as a condition in my GiD interface. The problem is that this geometrical property include approx 21 data:

identifier
prop1 to prop19

In this way, the corresponding generated file is very large due to the repeated information as:

elem1 prop1....prop19
elem2 prop1....prop19
elem3 prop1....prop19
...
elemn prop1....prop19

There is any way to write the information using the identifier included in my geometrical property in the style:

elem1 identifier
elem2 identifier
elem3 identifier
...
elemn identifier

with the corresponding geometrical property defined elsewhere ?

Thanks

Can define a condition, with an special field #MAT# , pointing to a material that store the common properties. 
some like this:
*.cnd

CONDITION:MyCond
CONDTYPE: over surfaces
CONDMESHTYPE: over body elements
  QUESTION:Property#MAT#(Properties)
  VALUE:Table
END CONDITION

Then the condition window at run time show a menu with the current available materials of the book named "Properties"

*.mat

BOOK: Properties
MATERIAL: Template
QUESTION:Type
VALUE:Template
STATE:hidden
QUESTION:Prop1
VALUE:0.0

This special auxiliar materials are located in a separated book (named Properties), and must not be assigned by the user to geometrical entities, draw, or unassigned.
Also the user must not delete the material named Template, used to create derivated materials, with this fields but other specific values

*.tcl

proc InitGIDProject { dir } {

  ChangeDataBehaviour

proc ChangeDataBehaviour { } {
   GiD_DataBehaviour materials Properties hide {assign draw unassign} ;#hide some buttons for all materials of this book

  *# write the material name

 if {[string equal "#SELECTEDSURFACES" $chaine] == 1} then {

  set values  ""
  GiD_AssignData condition Selection_of_Surfaces surfaces $values $ligne

 }
...

where Selection_of_Surfaces is the name of my condition and ligne is a
list deduced from the reading of a file.

I do the same for lines and points (using the same type of procedure)
and I have no problem.

Do you think that I made a mistake or there is a bug in GID 7.5.3b ? Is
there the same problem with the newest version of GID ?

Hello,

I tried a similar command, with GiD 7.5.3b, and the included sample problemtype "ansys55_3D" 

I creatde some surfaces, loaded the problemtype, and used

set values "1 0 1 0 1 0"
set ligne "1 3"
GiD_AssignData condition  Surface-Constraints surfaces $values $ligne 

And it assigned well this condition values to the surfaces 1 and 3

Check the value of your parameters $values and $ligne.
GiD_AssignData condition Selection_of_Surfaces surfaces $values $ligne 
- values must have the same number of parameters as in the 'Selection_of_Surfaces' condition definition ( see .cnd file)
- ligne must have a list of surface identifiers

Can use WarnWinText to debug your current values

WarnWinText "values=$values ligne=$ligne"
GiD_AssignData condition Selection_of_Surfaces surfaces $values $ligne

Thank you Enrique,

Every thing is right now : THERE IS NO BUG !

Nevertheless, note that my problem came from the definition of my
condition. In the .cond file it was:

    NUMBER 4 CONDITION: Selection_od_Surfaces
    CONDTYPE:over surfaces
    CONDMESHTYPE:over face elements
    QUESTION:Select#CB#(surfaces)
    VALUES:surfaces
    END CONDITION

This condition is cannot be assigned whenever I use the command
"Gid_AssignData condition". Actually, I must modify the property
CONDMESHTYPE "over face elements" with "over nodes" if I want that the
command runs !?! It was just for information, because I do not well

Hi Enrique,

I was wondering whether you had time looking into my files. In the meantime,
I have tried to create a nurbs surface from the triangulated one using
Rhino, as Rick Morgans kindly suggested in the forum. In Rhino, they
have several types of IGES formats that they can save the file into, i.e 3DS 
Max, CATIA, MechanicalDesk, Pro/E, Softimage, SolidWorks........... I used 
3d max 3.0, and the rendered surface came out funny in GiD, and I could not 
produce a volume, see attached file. May be, I was saving the file using an 
IGES format that is not compatible with GID. Can you help?

Thank-you very much!

Hello everybody again,

my question concerns the generation of a structured mesh using the
concentrate elements function. When using this function vector appear on
each line selected. Often the vectors point in different direction on
parallel lines, therefore the element concentration setup process has to
be repeated for the lines pointing in the opposite direction.

Is there any possibility to influence the direction of the vectors?

Regards

Hi,

Normally, latest GiD beta versions would have to point all vectors to the
same direction in "parallel" lines, as long as these lines owns to 4-sided
surfaces, in wich it can be recognised opposite lines ("parallel" ones).
If this is your case, please, send us the model to allow us to detect the
problem.

If lines does not belong to any surface, GiD actually does not recognize the
parallel lines, but we will work in this feature for next beta versions.

Note that you can swap line's normals before concentrating elements using:
- Utilities->Draw->Normals ContextualMenu->Swap Some  in old GiD versions.
- View->Normals ContextualMenu->Swap Some  in latest GiD beta versions.
So as all line's orientation points to the same direction, and as this way
will be drawn when concentrate elements funcion is called.

ABEL

Hi,

i just create a rectangle with the newest GiD version (7.6.0b). The
horizontal lines show the described behaviour, but the vectors of the
vertical lines point in opposite directions.

I tried to swap the normals of some lines by the way described by you,
but this doens't affect anything concerning the direction of the vectors
for concentrate mesh.
There seems to be an inconsistency with the vector orientation between
the "draw normals" and the concentrate mesh vectors (see pics attached)

Is there any possibility within the Tcl Extension to detect the
direction the vectors of lines point to?

Normally it appears when GiD tries to mesh a very thin space between two big

Hello GiD users
I have the following problem:

In my *.mat file I have entered the following:

Book:MaterialProp
NUMBER: 1 MATERIAL: XXX
QUESTION: E_Modulus:(E1,E2,E3)
VALUE: #N# 3 1.57D+11 1.08D+10 1.08D+10
END MATERIAL

corresponding entry in the *.bas file is:

Begin Materials
Nº Materials=  *nmats
YM
*loop materials
*format "%5i%16.10e%16.10e%16.10e"
*set var PROP(real) = MatProp(E_Modulus,real)
*MatNum *PROP
*end

obviously there is something wrong in the *.bas file because when I execute
the command " Export ---> Calculation File " it writes the *.dat file but
all the three E1,E2,E3 values are missing  and writes " 1  3.00000E0"
instead.

Could anyone suggest as to where am I wrong?
Thanking you

Thanks yor out answer. Sadly in my mesh i have to create new nodes, so even 
if there is a workaround my problem, the solution would take longer to 
create than just using our traditional postprocesor. Anyway if its good for 
anyone, what i have thought is to instruct the solver to write all the nodes 
in each step with new numbers, and append them to the mesh file, and since 
the notes that are not included in the solution are not shown we'll have the 
ilusion of having a moving mesh. That way we will have a HUGE mesh file, 
which i don't know if its practical or not. 
I guess i'll use another tool...
Greetings

Since version 7.5.3b it is possible to read several meshes inside GiD with
the option Files->Open Multiple
(http://www.gidhome.com/support/gidbeta/gid_14.subst#SEC193)

Which reads several .post.bin ( or pairs of .msh .res) at once.

Hi,

if the mesh changes during the analysis, like in adaptive mesh or remeshing
(i.e. the topology of the mesh changes) it's still possible to postprocess
it in GiD.

To do this, look at menu entry Files->Open Multiple ( help also at
'http://www.gidhome.com/support/gidbeta/gid_14.subst#SEC193').

Just write pairs of mesh&results files (as of if each pair were to be read
alone in GiD) and read them together in GiD with that option.

In other words: for instance lets say that you have refined the same
geometry/mesh 3 times, each mesh with their own results: like this:

Mesh 1: 5 analysis steps with results.

Mesh 2: 3 analysis steps with results.

Mesh 3: 2 analysis steps with results.

Then just write:

Mesh 1: file_mesh_1.msh, file_msh_1.res (with the results for the 5 steps),
or their equivalent in binary file_mesh_1.bin. 

Mesh 2: file_mesh_2.msh, file_msh_2.res (with the results for the 3 steps),
or their equivalent in binary file_mesh_1.bin.

Mesh 3: file_mesh_3.msh, file_msh_3.res (with the results for the 2 steps),
or their equivalent in binary file_mesh_1.bin.

You can manage each pair (.msh and .res) separate one from the other in GiD
with File->Open

Or view them together with File->Open multiple.

Remember two things:

It's preferable that mesh names should be the same ( so if in
file_mesh_1.msh there are the meshes "hull" and "ship", in file_mesh_2.msh
and file_mesh_3.msh both meshes should also be present). If not, when you
change the current step selection then on the layers windows some meshes
will appear and disappear (as they are present in the selected step or not).

It's preferable to have different step values for each mesh. If you write
mesh_1 and res_1 with the same analysis name and step value as mesh_2 and
res_2, only the latest results will be defined inside GiD, as the second
results overwrite the first one.

Enclosed you'll find an example of 9 meshes with their results. Open them
with File->Open Multiple by cliking on the first one and Shift-clicking the
last one.

Hallo gid team,

Appreciate to be advised how to set up correctly the "Copy Window, Transformation: Sweep" 

in order to get an extruded volume similar to the included example (forget the additional cuts), by sweeping the surface along the line as the defined path.

Thank you.

Hello Javier,

The current sweep tool has limited to select only a single path curve, you must join your multiple path lines: use collapse points, or create a polyline

Note: your model has some duplicated points, use also collapse to remove duplicateds.

Then you need to orient the path curve in the appropiate extrusion sense: use draw normals, and swap this normal if not agree with the desired sweep.

Then can use the sweep window: select surfaces as source, the path line, and extrude volumes. And select the source surface/s.
(when you select surfaces, the path line tangent is drawn to visualy check if it agree with the desired sweep)

Regards

Hi Enrique,

Thanks for your quick response. 

Following your instrucions I managed to get a swept volume, but for some unknown reason to me the geometry created does not strictly follow the defined path, see attached file where it can be seen what I have made.

I just got the geometry of the center, in place of the right one which was made with a third party 3D CAD and then imported via an iges format file.

Could you please tell me how I would get the right volume within GiD ?.

Thank you.

This is a corrected bug of some previous versions (you used 7.5.2b).
Update GiD to the last available beta 7.6.0b beta version.

I attach your model, including the sweep obtained with GiD (pink layer)
Note: I moved the source surface to the path line start.

Dear Sirs,

First of all, I want to congratualte you on the creation and development of a great product. Please keep up the good work!

I have one question concerning any known techniques to use GID to insert cracks in a mesh. I am looking for suggestions that will facilitate the insertion of 3-D cracks, either serrated, circualr or elliptical into a given geometry.

When will you recommend to do it: as a geometrical entity or in the mesh directly?

Your kind comments will be greatly appreciated

Hi,

There is no tool now available in GiD to take care about 3D cracks in meshes. We are working on it, but it won't be ready soon.

The only way to treat this problem now, using GiD, is to modify the geometry including the cracks, and mesh again the new geometry.

It exists a GiD-Tcl Info command to get this type of geometric information (coordinates, derivatives, etc): 

for example to get the u,v parameter coordinates of a 3D coordinates x,y,z on the surface number 28, can use

set uv [GiD_Info parametric surface 28 uv_fromcoord $x $y $z]

Hi Willy,
Your model don't have any geometric surface (you probably imported a mesh), then it not exists a "surface space parameter" to ask.

In other hand, the user don't have any control over the parameterization of the surfaces, then maybe the uv parameter space coordinates are not valid for your use.

I generated by revolution a new surface matching your simple mesh shape. I attach your model with this surface number 1.

Then you can ask for example the uv coordinates of all your nodes over this surface with this tcl procedure

proc GetUVCoordinates  { } { 
   set res ""
   set numsurface 1
   set infonodes [GiD_Info mesh nodes]
   foreach {num x y z} $infonodes {
       set uv  [GiD_Info parametric surface $numsurface uv_fromcoord $x $y $z]
       append res "$num $uv
"
   }
  WarnWinText $res
   return $res
}

To test it:
copy this definition procedure an put in the GiD lower command line, preceded by "-np-" (to indicate GiD that is tcl code)

-np- proc GetUVCoordinates  { } { 
   set res ""
   set numsurface 1
   set infonodes [GiD_Info mesh nodes]
   foreach {num x y z} $infonodes {
       set uv  [GiD_Info parametric surface $numsurface uv_fromcoord $x $y $z]
       append res "$num $uv
"
   }
  WarnWinText $res
   return $res
}

Then the procedure is defined inside GiD, and can invoke it with 
-np- GetUVCoordinates

(it will open a window with the results)

Note: It's possible to easily call tcl procedures from customized buttons of  the macros toolbar.

Hi Enrique
    Where should I put this tcl proc?? in which file
of GiD?or which directory?
Enrique what do you mean by <uv-parametric space>
here? isn't the x-y coordinate of 3D x-y-z cartesian
coordinates?
What is the idea of uv-parametric used in GiD? how
could I get this uv-parametric generated inside my
source code? instead of reading as a input file of
this uv data.. I just read the 3D xyz coordinates in
the data input file then write the source code to
calculate the uv-parametric automatically inside the
code..

Best regards.

--- Enrique Escolano <escolano at cimne.upc.edu...
For a fast test, it's not necessary to save the code in any file. you can
copy and paste in the GiD command line, preceded by "-np-" as I said in the
previous message:
-np- proc GetUVCoordinates...

And use with:
-np- GetUVCoordinates

A parametric surface is a mapping from a 2D parameter space (a 1x1 square)
to 3D coordinates.  { x(u,v) ,y(u,v), z(u,v) }
Maybe you can use this u,v space.

Note: each surface has his own parametric space, then you only can use this
trick if your 3D nodes are generated from a single source surface.

In general, only from a cloud of points you can't create a surface to use
his space parameter.
The uv_fromcoord command get the inverse: from a 3D coordinate on the
surface, returning the u,v parameters
(to calculate this inverse of the parametrization, you need to solve a
non-linear two equation system, finding u,v that minimize the distance to
the 3D point)

Hi Enrique
    The proc you wrote gives the window box of Copy, Translation, mirror, scale, and offset... What and how can I know anything about uv-parameter from this window box. Actually we use this box only for extrution purpose?? Would you please to elaborate.

Hi, from what you are telling, it's sure that you have selected de Tcl code
from the mail, made a ctrl.-C and change to GiD, and pressed Ctrl-V to paste
the code in the command line entry. But, in gid, Ctrl-V is the shortcut for
the Move window, which will popup and that is what happened to you.

Instead of using Ctrl-V to paste the code, used Shift-Insert. 

But, as Enrique told you, you'll need a Surface to get's this UV information
and in the example you've sent, there is no geometrical surface. So you'll
not get any UV information.

Hi GiD team,

See attached an imported lug.wrl file showing a 3D part structered mesh created in other solver platform. I have reproduced the geometry with same volume distrubution in GiD (lug.gid file also included), as it was the base for creating the structered mesh.

Question no1:
I could not generate an structered mesh of the 3D part within GiD, could you please tell me how it can be done.

Question no2:

Would it be possible to use the imported lug.wrl meshed file as the model wherein to run structural analysis with Ram series?, in other words, how to apply loads and constraints on meshed elements and not on surfaces as the standard way.

Thanks.

Hello Javier,

About the 1st question: the volumes 3 and 4 have 7 faces, it's possible to obtain a semi-structured mesh of prisms (than can be automatically splitted to tetrahedras), but not a structured one (it's necessary 6-faced volumes).
Can divide this volumes in two parts with exactly 6 faces.

About the 2nd question: If you directly import this VRML mesh, they are obtained triangles and some line elements (that probably must delete). 
To analize as a solid you need a volume mesh, not only the boundary triangles. 
If you want to analize as a collection of shells, you can directly apply conditions (loads, etc) to mesh entities instead to geometric entities, but in general this last option is unrecommended.

Hi there!

If i have a .igs model and i need both a triangular model and a tetrahedral
model to be generated, but they MUST have the same nodes defined and in the
same order. Is that possible with GiD? How? When i try i get a small
discrepancy in the number of nodes, but somewhere around halfway through the
nodes the ordering of them changes significantly.

It might sound strange, but what i need is a tetrahedral mesh, all surface 
nodes, with 2d
texture coordinates. If any of you have a better tool, then i'm all ears :)

Thanks in advance.

Dear GiD-Users and Developers,

I have a problem with generating reinforced concrete members. I want
to define concrete volume elements with line elements for the steel
reinforcement. Both types of elements have to use the same nodes where
the reinforcement is located. I tried to solve the problem by defining
two exactly located lines, one to define surfaces/volumes for the
concrete elements and one for the line elements, but GiD meshes them
differently ...

This should be a common problem for everybody, who works in the field
of civil/structural engineering. I also could think of meshing in two
steps, first the reinforcement, then the volume by defining the nodes
of the line elements as fixed for the mesh ceneration of the volume
elements but GiD doesn't have this feature ... ? To demonstrate the
problem, I attached a model of a concrete slab with reinforcement ...
(it's just half of the model because it's symmetric)

Any suggestions? Thank you in advance.

Hello, Soren,

GiD meshes the geometrical entities hierarchically. It means that when a
volume have to be meshed, first of all, all its contour surfaces are meshed,
wich, at the same time, needs its lines meshes to be meshed.
The problem you have is that the lines that define the steel reinforcement
are not part of the volume (topollogically). If you want that lines meshes
share nodes with volume elements, the only way to do it is to create
surfaces owning the lines, and split the volume in different volumes
(smaller), with that surfaces as the contour ones.

Regards,

                                                    ABEL

Hello Soren & Michael,

As Abel remarked, to obtain tetrahedras with nodes on the lines, it'
necessary that this lines are in the boundary of a surface, that is in the
boundary of the volume.  Several "steel" lines are not each other
intersected, then will not be generated a common node, you also need to
intersect this lines if they are really connected.

In other hand, by default, when GiD generate for example a mesh, then are
not explicitly created the "lower hierarchy elements", for example, when
generate a tetrahedral mesh from a volume, are not created triangle, or line
elements.
To force to have this "lower hierarchy elements", you must assign this
criteria to the desired geometric entities:
Mesh->Mesh criteria->Mesh-> Lines or  surfaces
They will be generated also triangles and/or lines, but will not be
generated any new node, they are shared with the tetrahedral ones.

Enrique Escolano

Well, in post there is the 'points' display style which draws points or
spheres at the nodes (Options->Geometry->Point options).

But to achieve what you see at your picture, the only way I see is to create
'point' elements on your nodes and 'line' elements on your edges.

Something like this (just 2 balls and 1 edge):

MESH "balls" dimension 3 Elemtype Point Nnode 1
Coordinates
1 0.0
2 1.0
End coordinates
Elements
1 1
2 2
End elements

MESH "bars" dimension 3 ElemType Lineas Nnode 2
Coordinates
End Coordinates
Elements
1 1 2
End Elements

If you want to change the balls and lines visualization, just use the
"Options->Geometry->Points options" and "Options->Geometry->Line Options".

Hi Miguel
    I tried what you gave me an example but it didn't
work out..especially the .msh file and I never saw
such commands you have given here.. Any further
suggestion??

Hi,

is there a possibility in GiD to visualize scalar and vectorial results 
with logarithmic scaling (e.g. acoustic pressure)?

By now the only way to operate results is through Tcl-Tk, with

GiD_Result get {"pressure" "acoustic analysis" 1.0}

Operate this result in order to change its scale and then

GiD_Result create {Result "Log pressure" "acoustic analysis" 1.0 scalar
onnodes} {node_id_1 value_1} {node_id_2 value_2} ...

You can find more info here (Tcl-Tk extensions->Special functions): 
http://www.gidhome.com/support/gidbeta/gid_18.subst#SEC293
 (look for GiD_Result)

Hello,

does somebody know how to hide the coordinate system by plotting results in picture files like png or gif?

Thanks in advance

Rafael

There is a "dark" command to show/hide this axes:

escape escape escape view hardcopy options _showaxes

Hello,

I'm using Gid 7.6.0b. When I make Utilities -> list -> Points and pick a point belonging to 3 lines I get the folowing result:

POINT
Num: 3 HigherEntity: 3 conditions: 1 material: 0
LAYER: Layer0
Coord: 0.000000 5.000000 0.000000
END POINT
POINT (more)
Higher entities points: 1 4 11
END POINT

But I think it should be lines instead of points in: Higher entities points: 1 4 11

Best regards,
Mihai TEODORESCU

Yes, the correct message must be: "Higher entities lines: 1 4 11"

Thanks for your bug report

Hi everybody,

when creating a mesh, GiD complains about

"There are elements with negative jacobian in some node in surface 1 mesh"
"There are elements with negative jacobian in some node in surface 2 mesh"

Steps to reproduce this behaviour:

# creating geometries
# - create two rectangles
rectangle 0,0    8e-4,1e-2
rectangle 0,1e-2 8e-4,46e-2
# - create a quarter of a circle
utilities copy lines DoExtrude surfaces MaintainLayers Rotation FJoin 2
TwoDim -90 2 escape

# set import tolerance
utilities variables ImportTolerance 1e-6

# collapse model
utilities collapse model yes

# renumber all entities
utilities renumber yes

# setup the mesh
# - structured surfaces of the rectangles
Meshing Structured Surfaces 1 2 3 escape 4 2 4 escape 3 1 3 6 escape
# - select quadratic elements
Meshing quadratic Quadratic

# generate mesh
Meshing Generate 4e-3

==>

When creating the mesh, the messages about the elemtents with negative
jacobian appeear.

This doesn't happen, when i don't use structured surfaces.

But the question is: If GiD already knows about elements defined in the
wrong direction meaning clockwise, why does he not correct the wrong
elements instead of telling me that there have been mistakes along the
element definition.

Regards

Martin Meiler

Hello,

Thanks for notifying us this behaviour. It is now corrected, so it will be
available to you in the next beta version, that provably will be ready in
this week.

Hello,

I don't understand what do you want.
What they contain ProblemTypePriv(pointnames)  and ProblemTypePriv(facenames) ?
a list of names? like ProblemTypePriv(pointnames)="a1 {a 2} a3", ProblemTypePriv(facenames)="b1 b2 b3"
and do you want ProblemTypePriv(combo)="a1 {a 2} a3 b1 b2 b3"? Then you can use some like "concat":
set ProblemTypePriv(combo) [concat $ProblemTypePriv(pointnames) $ProblemTypePriv(facenames)]

if you want to store two sublists: ProblemTypePriv(combo)="{a1 {a 2} a3}  {b1 b2 b3}", can use "list"
set ProblemTypePriv(combo) [list $ProblemTypePriv(pointnames) $ProblemTypePriv(facenames)]

Hi, under the page:

http://www.gidhome.com/ManHtml

we've post the Manual Pages for Tcl, Tk and some packages we use incide GiD,
like Tcl & Tk:

http://www.gid.cimne.upc.es/ManHtml/tcl8.4.9/html/contents.htm

BWidget: (comboxes, notebooks, etc.)

http://www.gid.cimne.upc.es/ManHtml/BWidget/index.html

And for the combobox:

http://www.gid.cimne.upc.es/ManHtml/BWidget/ComboBox.html...
Thank you Miguel.
But the value X is not always 10 or 0. Is the value we write in entry for X. 
Next you have some lines of my code:
proc tkpoint::initwindow { parent GDN PARENT} {
    set lx [label $parent.lx -text "X:"]
    set ex [entry $parent.ex -textvariable tkpoint::x -width 10 -bd 2]
 tkpoint::InicioJanela $PARENT $GDN
}
proc tkpoint::InicioJanela { parent GDN } {
    global ProblemTypePriv
    global wdataw
         (...)
    set ProblemTypePriv(pointcombo) [combobox $wdataw.f1b.c -editable 1 
     -keephistory 0 -history $lcns -textvar ProblemTypePriv(pointcombotext)]
    $wdataw.f1b.c del 0 end
    $wdataw.f1b.c ins end $cname
    $wdataw.f1b.c conf -editable 0
    GidHelp $wdataw.f1b.c "This is a list of all created point loads. In this menu it is "
     "selected the active point load."
    trace var ProblemTypePriv(pointcombotext) w "ChangeToPointCombo ;#"

  (ChangeToPointCombo is equal to ChangeToLoadCase of Load Cases in Nastran, where we have the possibility of create a new point load, rename or delete)

    button $wdataw.f1b.b1 -image $ProblemTypePriv(loadcaseimgcheck) -padx 0 -bd 1 -pady 0 
     -command "NewPoint {} $wdataw"
    button $wdataw.f1b.b2 -image $ProblemTypePriv(loadcaseimgrename) -padx 0 -bd 1 -pady 0 
     -command "RenamePoint $wdataw"
    button $wdataw.f1b.b3 -image $ProblemTypePriv(loadcaseimgerase-cross) -padx 0 -bd 1 -pady 0 
     -command "DeletePoint $wdataw"

    (...)
}
Supose we create the point load P1.
Then we write on entry $parent.ex for example 10, it could be any other value.
Therefore, i want to have one button, that when we click on it, the written value can be saved.
What i want is: Supose i create a new point load, for example P2, with the same values of X or different
from P1. After saving this values, i select in combobox the point load P1, and in $parent.ex appears the
the values of X saved for P1, and not the values of P2.
I think that this button will be similiar to the button "Update Changes" in the Material's menu.
Thanks

With the option –modifycmd you can specify a tcl procedure which will be called every time the user selects one entry of the combobox,

Here you have an example:

set ::XValue -1
set ::XValueStr "XValue is $::XValue"

proc ChooseXValue { w} {
    if { [ string eq $::LoadSelection P1]} {
            set ::XValue 10
    } elseif  { [ string eq $::LoadSelection P1]} {
            set ::XValue 0
    }
    set ::XValueStr "XValue is $::XValue"
    tk_messageBox -message "XValue set to $::XValue" -icon info -title "Info" -parent $w -type ok
}

toplevel .w
ComboBox .w.cb -textvariable ::LoadSelection -values {P1 P2} -modifycmd "::ChooseXValue .w.cb"
label .w.l -textvariable ::XValueStr
button .w.b -text Close -command "destroy .w"
grid .w.cb -sticky ew
grid .w.l -sticky ew
grid .w.b
grid rowconfigure .w 0 -weight 1
grid rowconfigure .w 1 -weight 1

miguel

De: ...
The Miguel's code is only a sample with fixed values (0 or 10), but you can have stored 
your validated values inside a tcl array variable, using for example the combobox item as key index

proc ChooseXValue { w } {
    global MyLoadValues
    set XValue $MyLoadValues($::LoadSelection,x)
    set YValue $MyLoadValues($::LoadSelection,y)

    ...  update the desired widgets (setting his linked variables, or his widget properties)
}

Hello,

By the moment, using GiD, it's not possible to generate hybrid meshes of hexahedra and tetrahedra. Each geometry entity must have one, and only one, element type, and you can obtain hexahedra and tetrahedra meshes in the same model, but each element type associated to different geometry entities.

after installing the new beta of GiD, version 7.7b on a SuSE Linux 9.1

Hi, 
the problem is that gid.exe can not find the file tk.tcl. ¿which access
permission does this file and the whole path
/home/software/gid-beta/scripts/tk/ have?

¿have you installed GiD (ungzipped, untared and done: './install
/home/software/gid-beta/') as a different user?

miguel

ps. I use also the opportunity to tell you that you have also to rename a
file, scripts/tkhtml/libTkhtml.so to scripts/tkhtml/libTkHtml.so (note the
capital 'T' ant 'H' of the library name) so that gid can show up the html
help. (my mistake)

Hi again,

I've installed as root user, on a nfs- partition.
Read permissions are set for all users. Also the excecution permission 
is set for all.

Grepping the script directory reveals that function LoadGidAddons is 
defined, in tcltk_addons.tcl in the scripts directory, read permissions 
set to all users...

Any ideas?

Greeting Bjoern

PS: I'm using gentoo, tk and tcl is installed.

Hello,

when I load a .post.msh-file with about 400 000 nodes and 300 000
elements into GiD 7.7b (SuSE Linux 9.3), it starts reading the file
(progress bar reaches 100%) and after a few seconds GiD exits and I get
the following error message:

---
gid.exe: Post/utils_post.cc:1558: int TclAppendExternalResult(Tcl_Interp
*, char *, char *): Assertion `strlen( buf) < 8192' failed.
Abort
-----

The mesh is in 3D. The original mesh (created in another pre-processor)
contains tetrahedra, hexehaedra, wedges and pyramids. In our simulation
kernel I convert all of them to degenerated hexahedras with 8 nodes and
write them out into a .post.mesh-file with the GIDPOST-library (ASCII).
For smaller meshes this seems to work just fine. Do you have any idea,
where the problem might be?

Another aspect of the grid: We are not using the material parameter to
distinguish different regions in the mesh, since we want to see the
names of the regions, instead of a material number. Therefore we write
for each region a separate mesh with an own name and an empty
'Nodes'-section and one dummy-mesh which contains just the nodal
coordinates without element definitiosn. In this particular mesh there
are about 350 regions (=Mesh-sections). Might this be the limit in this
case?

Regards
Andreas

Hello,
o.k. thanks for the information, corrected. It's because of the large number
of meshes. To avoid the error ¿is your 'View style' window open? If so, just
don't open it. You can still use the right buttons menu to switch meshes on
and off.

There is no limit in the number of meshes. GiD supports tetraedra, hexaedra
and wedges.

It's o.k. the way you are writing the mehs. In fact you can also include de
nodal coordinates inside the first mesh, so you don't have to write the
dummy mesh.

In think that in a short time we'll release a new beta version.

I don't understand well what do you want, but you can't easily modify a condition to work like a material.

I will explain the GiD material/condition philosophy:
Internally, the gid entities points to a material (and only one), and you can modify some material property.
you can create a new material, derivated from another material, but with different field values.

The conditions are not pointed by entities. You create new instances of a template condition with his own values (it's like a new material), and this instance points to a list of entities. Then you can´t modify the values of an applied condition, because the conditions window show the condition template, not each instance that have different values. An instance of a condition has not an identifier to be modified, you only can delete instances applied to some entities, and create again.

It seems that you try to set for an condition instance, an identifier (the values that you store in ProblemTypePriv(pointnames)), and try to use this identifier to draw, modify, etc this instance.

Usually do you have few materials, but maybe a lot of different condition instances 
(it's a bad design to show a combobox with 300.000 identifier entries!!)

How do you define in the .cnd file the PointLoad condition?

Maybe you need to add a field to be used as identifier.
- You want to draw by color a field condition (the identifier field),.
- You must also control that when you create a new condition instance (when assign), the identifier 
   is not repeated with other different field values.
- To simulate that you modify a condition instance, you must unassign this condition of his entities, and assign again to the same entities with the new values 
Note: currently is not possible to unassign the condition with an specified field value of some entities, you  unassign the contition to some entities without any control over the field values. This feature will be implemented for next beta versions.

Hi,

Are you sure that results at gauss points is working properly for quadratic
Prism elements?

Linear Prism with only 1gauss point is ok but I think that quadratic Prism
with 6 gauss points doesn t work for "Natural Coordinates: Internal" neither
for "Natural Coordinates: Given".
I send you a simple example.
Thank you

Hello,

It seems that exists some problem when mixing different gauss point definitions.

About your sample, the Given Natural Coordinates are wrong (they define 6 gauss points, but are provided 12 coordinates)

In other hand, some features are currently missing for prisms.

- The "internal" gauss points was not documented in the help (we added now for the next beta version)

For linear prisms, the 6 gauss points GiD internal normalized coordinates are:
( a, a, b) 
( b, a, c) 
( a, b, c)
( a, a, d) 
( b, a, d) 
( a, b, d)
a=0.166666666666666, b=0.666666666666666
c=0.211324865405187, d=0.788675134594812

- The quadratic prism, with 15 gauss points is not implemented in postprocess, it will added in the related next beta.

Note: for a given number of gauss points different of the number of nodes (for example 6 gauss points with quadratic 15-noded prism), the results cannot be extrapolated to nodes (they are less equations than unknown values), and the results will be shown as balls on gauss points, instead contour filled. 
Maybe it's better to write, for postprocess pourposes, an alternative linear mesh (6-noded prisms).

Thanks for your example, it's very interesting to detect and correct this bug.

Hi,

Well at the beginning there was no support for quadrilateral prismas, but
more and more we’ve added support for them, and the same happened for the 6
gauss points on those prismas.

The bugs have been corrected and will be available on the next beta version.

Note that when giving the results only for 6 gp on a 15node prismas, gid
will extrapolate the result to the 6 vertex of the prisma, and then a linear
interpolation will be done to get the results for the middle (quadratic)
nodes.

Dear GiD Team.

I try to install last version (7.7.0b) of GiD for Linux.

By generating the password of previous version, I got as machine:poseidon.naoe.hiroshima-u.ac.jp.

By generating the password of new version, I get as machine:
poseidon only.

So:

1. if I enter poseidon as machine name in the website (for creating a password) an error message appears saying that the license is registered   for the machine poseidon.naoe.hiroshima-u.ac.jp.

2. if I enter poseidon.naoe.hiroshima-u.ac.jp as machine name in the website (for creating a password) a password will be created.
However, by passing this password to GiD password window an error message appears saying that there is an integrity problem.

What do you recommend as solution?

Thanks in advance

Dear Gidlist

I am trying to mesh two volumes; one that is discretised using structured prisma; and one that is discretised using unstructured tetrahedral. These two volumes should be conforming

Two standard error messages within Gid are

1. "Non-structured volumes can only be tetrahedra or only points". 

2. "Structured volumes can only be hexahedra" 

How exactly can I use Prisma then? All my surfaces are Nurbs.

Apologies if this is a naive question.

Many thanks in advance

Hi, Tim,

As you said, it is possible to select Prism as element type, but it had only
sense for contact volumes in version 7.2.
In lasts beta versions it has been added the option of meshing standard
volumes with prisms as element type (only prismatic volumes).
You can download the last GiD beta version from the web page
(www.gidhome.com).

Hi gid team
Is there any new on being able to plot the interpolated value of a variable
along a defined contour/line?
I still cannot do it in 7.5.8b (win2000 sp4).
regards
mark

In gid v. 7.7.0b there is the option 'View Results->Graphs->Line Graphs'
which plots a result along a line by choosing two points of the mesh.
By now it works on Volume meshes and planar surfaces.
¿is that what you want?

Hello,

i would like to know how to visualize (animation in fluid dynamics)
pressure and velocity on a free surface at the same time.
Like at page 166 of GID Reference Manual Version 7. There is no enough
explanation on the topic.

thank you

abdou

Hi,
Just inside the 'Several results window', which appears by choosing the
'Window->Several results...' entry on the top menubar, inside this window
select the 'one over another' radio button and press the apply button.

Then each different result view you choose will be stacked above the
previous one.

In the picture, first a deformation was done, then a contour fill of
'relative thickness', then vectors of the 'shell force' were displayed and
last, it shows the minimum and maximum value of the 'relative thickness'.
In the 'several resuts' window all the result views are shown inside the
listbox.

Hi,

we would like to order licences of GiD for our institute, but I just
saw in the announcement for the 3rd GiD Conference that GiD 8 will be
available next year.

Could you please tell me when GiD 8 will be available. Is it possible to
buy licences for GiD 8 in advance?  How much would an update cost?

Thanks a lot for your information.

Hi everynody,

i'm using GiD Version 7.7.0b on a SuSE Linux 9.3 machine.

The following bug occours during mesh generation:

Elements are defined wrong, so that a negative Jacobi Determinant is
reported by our simulation program.

This it is not GiD that reports the error, but still produces it.

Proof of bug:

create a line, i.e.

line from 0,1 to 0,2

then rotate this line my -90° using the copy menu using the
2D switch, rotating around 0,0 - extruding surfaces.

Create a mesh and look at the element definitions.

They are clockwise.

Then switch to geometry view, and switch the normal of the surface you
previously created by extruding.

Remesh

The elements are now defined counterclockwise and everything is fine.

Regards

Martin Meiler

You are rigth, but it's not really a GiD bug.
In general, specially in 3D space, it's valid that the normal points to any
direction.

You can have a surface in the XY plane with normal pointing to +Z , but you
can move
this surface (for example rotate 180 degrees arount the X axe) then the
normal now points to -Z.

In other hand, to facilitate the use, when GiD create a surface in the XY
plane, it usually automatically set
the orientation to point to +Z, to avoid orientation problems (negative
determinants) for 2D FEM solvers.

In any case, the user (or automatically the problemtype) must check the
surfaces orientation (GiD has tools to draw by colors, swap, etc).
Note: The elements orientation is the same as the source surface orientation

Hello everybody,

when applying our problemtype we define within our conditionsfile (.cnd)
the following condition:

NUMBER: 161 CONDITION: Line_Elem_Labels
CONDTYPE: over lines
CONDMESHTYPE: over body elements
CANREPEAT: yes
QUESTION: NameID
Value: 0
END CONDITION

This should realize boundary conditions defined by 1D line elements.

We later on use

GiD_Process data cond assign Line_Node_Labels change 1 17

that should apply this special condition to line 17 and index this
condition with index 1

This works quite fine for just one line, but if we define the same
condition to more than one line, like

GiD_Process data cond assign Line_Node_Labels change 1 17 18 19

or even

GiD_Process data cond assign Line_Node_Labels change 1 17
GiD_Process data cond assign Line_Node_Labels change 2 18
GiD_Process data cond assign Line_Node_Labels change 3 19

we obtain the following error when generating the mesh:

Condition 'Line_Elem_Labels' has flag 'on elements' and maybe it needs
flag 'on face elememts' in the .cnd file in the problem type
2.5
Error when transfering condition 'Line_Elem_Labels' from geometry to
mesh in line 12. It has not been transfered.

Well, where is my/our error or what does GiD want to tell me by this
behaviour.

I'm using the actual GiD 7.7.0b Beta version.

Thanks for your help

Regards

Martin

Hello again,

i resolved the problem and it has its origin in using the function

GiD_Process

I have an array containing the entities for a certain element boundary
condition.

I use the following command

GiD_Process Meshing MeshCriteria Mesh
$bndryRegionData(selType,$regionNo) $bndryRegionData(entities,$regionNo)

and i can see within the Undo history, that i.e. the following has been
executed

Meshing MeshCriteria Mesh 1 "1 15"

If i use .central.s process instead of GiD_Process, then

Meshing MeshCriteria Mesh 1 1 15

is executed by GiD.

So is there a difference between the use of GiD_Process and .central.s
process ?

Concerning the mentioned problem, i now understand what happened:

This behaviour didn't create 1D line elements and therefore the
condition assigned to the line couldn't be mapped from the line entity
to the refering mesh elements, because they didn't exist.

Thanks for an answer to the difference between GiD_Process and
.central.s process question

Regards

Martin

There is an importand difference between GiD_Process and .central.s process:
GiD_Process preserve his number of parameters, and they have standard tcl list syntax
.central.s process split the parameters in separated words if they include spaces

Usually the GiD commands are single words, but sometimes they have spaces (for example a filenames, layernames, etc)
It's difficult to use .central.s process if his parameters can include spaces , it's necessary to add additional quotes

for example if you use:

set filename "C:/My   dir/test"
.central.s process escape files read $filename

The command fail, because filename is splitted in two words "C:/My" and "dir/test", then GiD can´t open the file "C:/My" and unknow the other command "dir/test"

You must use some like this to avoid this problem:

if { [llength $filename] > 1 } {
   # if include spaces must be enclosed with additional quotes
  .central.s process escape files read "$filename"
} else {
  .central.s process escape files read $filename
}

The best option is to use the new GiD_Process command

GiD_Process escape files read $filename

In your case, you set a variable with several GiD commands, for example 
set cmd "escape escape geometry create point 1.0,1.0,0.0"
if you use
.central.s process $cmd 
it works, because $cmd is splitted in 6 words "escape" "escape" "geometry" "create" "point" "1.0,1.0,0.0"
and
GiD_Process $cmd 
fail, because "escape escape geometry create point 1.0,1.0,0.0" is traited as a single word
A trick to solve this problem using the Tcl eval command to split $cmd before be send to GiD_Process
eval GiD_Process $cmd 
Note: For this useful problem, the future Tcl 8.5 language will include an special command {expand}to split arguments,
then in the future can be used some like: GiD_Process {expand}$cmd

Concluding, It's better to use GiD_Process (.central.s process will be deprecated)

I don't know what's the problem
When you press draw for example, all condion window widgets are temporary set to disable callint the GiD procedure
RecursiveChangeState $w disable
But when press finish, they are restored to the previous state with
RecursiveChangeState $w restore

In other hand: some advices:
- "combobox" is an obselete, pure tcl, megawidget. You can use instead the "ComboBox" widget of BWidget (note the Upper C and B letters). Off course the use syntax and properties are differents.
- You NEVER must directly modify any tcl file located inside /scripts of GiD !!
  else you need to modify this scripts each time that you update to a new GiD version.
  You must add your own tcl code in your problemtype scripts. 
- In order to modify the body of the GiD standard Conditions window, don't directly remove and add widgets, 
  must use TKWIDGET (read GiD help about TCL-TK Extension - Custom data windows)

Hello,

1) As I remarked in my previous GiDList message: must NEVER modify the GiD
tcl scripts !!
2) I also recommend to not modify the standar toolbars (changing variables
used in GrDataMenus, etc), else probably your problemtype will not work for
the proper next version, because we don't know your changes. If we simply
rename a variable your code will be broken.
3) You can see a simple example of Tcl/Tk customization at
http://www.gidhome.com/2004/material_courses.subst
    Read chapter 08-Tool of mesh edition  (it creates a new toolbar)
4) Each user can modify, without programming, the standart macros toolbar,
adding customized icons to invoke their own commands

Then, at you problem_type.tcl just call MyNewBarProc to display your bar.

The first time it'll appear as a standalone window, but if you right-click
above it and select 'configure toolbars' you can change the place of you
icon bar. With this example, the name 'My new bar' will appear in the
listbox.

I have a simple 2D model which is quite small fits inside a 0.64x4.6
rectangle, it has some small features e.g. a 0.02 fillet and a 4.0x0.032
rectangle, when I try to scale the object by a factor of 0.001 certain
features disappear? i.e. the fillet and some lines why? I have tried setting
the import tolerance to something very small but it make no difference.
it even happens on a 1x1 square (delete surface) with a 0.01 fillet then
scale by 0.001

regards
mark

Hello Mark,

You must select the "Duplicate entities" copy/move option,
then the entities are always created, without compare to be joined with
other near entities.

(unselectign duplicate entities will be made like a collapse, with a fixed
tolerance)

Hi,

I would like to export the linear part of the connectivity of a quadratic 3D 
mesh using 20-noded hexahedron. In other words, just the vertex nodes. 

The linear part will be used for mass transfert using finite differences and 
the obtained results transfered to a mechanical finite element problem using 
the quadratic mesh.

Thanks

In GiD the element nodes are ordered first the "linear part", and then the
quadratic nodes (hierarchical numeration)
for example, for a 20-noded hexahedral, the corner nodes are the first 8
nodes.

For example, you can print only this nodes using a bas template like:

*loop elems
  *elemsconec(1)   *elemsconec(2)   *elemsconec(3)   *elemsconec(4)
*elemsconec(5)   *elemsconec(6)   *elemsconec(7)   *elemsconec(8)
*end elems

Hello,

i have a problem with the assignment or better the unassignment of regions.

In the conditions file i define:

NUMBER: 161 CONDITION: Line_Elem_Labels
CONDTYPE: over lines
CONDMESHTYPE: over body element
CANREPEAT: yes
QUESTION: NameID
Value: 0

In GiD i assign values by using

data cond assign Line_Elem_Labels change $nameId $entities

i.e.

data cond assign Line_Elem_Labels change 2 7 12

if i change my model setup and want to remove this specific condition
identified by nameID 2 and line 7, what do i have to do?

If i use unassign, all my conditions are gone. If i you remove a new
condition is created.

Thank for an answer

Regards

Martin Meiler

At this moment you can unassign some condition from some entities, but  it is not possible to use 
a selection criteria based on condition field values.

e.g.
you can unassign the condition named 'Line_Elem_Labels' from the entities 7 and 12 with:

Mescape data cond assign Line_Elem_Labels unassign 7 12

but you can't unassign the condition named 'Line_Elem_Labels' only with the field 'NameID' = some value from some entities
e.g., if you have this condition applied twice over the same line number 7 with different values, for example 'NameID'=A and  'NameID'=B
you can't unassign only the condition with  'NameID'=A. 

If you use
Mescape data cond assign Line_Elem_Labels unassign 7
you will unassign all 'Line_Elem_Labels' conditions applied over the line 7

Note: Mescape is an special word that send all escape as necessary, to go up until the top node on the commands tree.

If you used only pure Tcl/Tk (without any compiled extension), then your problemtype 
must works well, without any change, on Windows, Linux, MacOSX, or Unix.

But probably you must add an analisis program specific for each platform
(and also add an .unix.bat file with Unix/Linux like operating system commands to rename files, etc and start the solver)

Hello!  we are working on linear elements and we can´t define the gauss point by
the new postprocess method in the .flavia.res file.
The problem is that the values which corresponds to the elements are being
assigned by GID to the nodes. We need a right definition of the Gauss point for
this type of elements.
We were reading the help menu, but we get an error defining the gauss point as
it explains there.

Best Regards,

Franco Giuggioloni

What's the error that you gets when defining the gauss points?
Can send us a small zipped example of your .post.msh and .post.res (or
.flavia.msh .flavia.res)?

What's your GiD version? (see help->about)

Please, if your model is big, don't send to this GiDList, send directly to
escolano at cimne.upc.es

It seems that it not exists any element with this condition.
Are you sure that do you have some element have this Localaxes condition applied over them? 
Use draw condition when visualizing the mesh.

After apply to geometric surfaces, must generate again the mesh to transfer to the elements.

What type of elements do you have: surface elements (triangles or quadrilaterals) or volume elements (tetrahedras, etc)?

In other hand, your "Localaxes" is only the name of a condition, but don't use the GiD local axes internal concept 
(read help about #LA# fields).

Hi,

system this is no problem, but GiD for Windows does not accept the link.

What I would like to achieve is:

You can create a link from a Tcl command like this (also works for Win NT/2000/XP)

put this line in the GiD lower command line some like this (using your own paths off course), and press return
-np- cd {C:Program filesGiDGiD 7.7.2bproblemtypes}; file link -symbolic MyProblemtype.gid {C:other directoryMyProblemtype.gid}

It will create a link inside the C:Program filesGiDGiD 7.7.2bproblemtypes directory, pointing to C:other directoryMyProblemtype.gid

Note: this link is different of  "direct access" Windows links, and it looks like an useful directory, not like a Windows link.

Must be careful, it seems easy to confuse the "real" and "link" directories:  if you delete this "link", don't delete 
the files inside the "real" directory.

Maybe we can also support "Windows links" for next GiD beta versions.

Thanks a lot for this advice.  It works very well, unfortunately not for
network directories.

Maybe it is also an option to make the problemtypes directory path a user
definable variable (maybe even a list of directories) in future. No need
for links then, one can simply include all directories with problemtypes.

Thanks again.

Yes, it is possible. 
You must check the option Symmetrical Structured Triangles in Preferences->Meshing menu.
I think this option is no available in the GiD version you use (7.2); in this case you must update it from our web:

The 7.2 is not a beta version, is the current official 7 version. 
Beta versions are more modern, and then some features (GiD_DataBehaviour, etc) only exists in the last beta versions, but not in the official 7.2 version.
The current last available beta version is the 7.7.2b

In other hand, when you buy the 7.2 version, the password is also valid for all 7.x beta versions. 

We are planning to release the GiD version 8 at the 2006 begin. This version will include all last features.

  Hello

  I have stress and strain data at the gauss points and displacement data at the nodal points. I can get it read by the GID post processor. Displacements at the nodal points can be plotted correctly. However, I cannot plot the stress and strain data at the gauss points. It does seem to read the gauss points as it displays the maximum and minimum values of stress and strain in the command window. But it shows some weird contour range values. And it doesn't plot the stress strain data. My model is a  3D model, so the gauss points are inside the surface of the solid model. Is the color of the 3D solid model blocking the contour fill of the gauss point data? Because all I can see is the solid color of the elements.

  It would be a great help if anybody can suggest me how to overcome this problem

  with regards
  Rabin

First of all, check your GiD version. The last beta versions have a lot of features and corrections related to gauss point results that not exists in previous versions.
The last available beta version is the 7.7.2b. If you have an old version, update it from our web: http://www.gidhome.com/download/do07.subst

If the problems are not solved with this last version, send us a small sample (results and mesh file) to check if it's correct.

In my application I need to generate a surface mesh which represents the solid 
boundaries in an assembly composed of several parts (imported as ACIS files). 
The contact surfaces (the interface between adjiacient solids) must generate 
a common mesh and the mesh file should include the information on the solids 
connectivity. Furthermore I need to have a mesh that is composed of cubic 
elements (10 points triangles). 

Is it a way to get all this data structure using the GiD software ?

Thanks
Walter Steffe

As I underestand, you don't need volume elements (tetrahedrals or
hexahedrals), you only need the surface mesh (triangles)
But in other hand, you said that "should include the information on the
solids connectivity" ??

If you need to have both: volume, and surface elements,  can force the
surfaces to create elements with
(menu:  Mesh->Mesh criteria->Mesh->Surfaces, and select the surfaces)
(by default, when are generated the volume elements, the surface elements
are removed)

If you need a common mesh between parts, you must collapse the common
surfaces in order to have a single surface (shared between volumes if you
need also volume mesh).

If you need a different copy of nodes on each body, maybe you need to create
a GiD "Contact volume" between two surfaces, in order to force to have a
similar mesh in this two surfaces. (menu: Geometry->Create->Contact volume)

About the cubic elements, GiD only can manage linear or quadratic ones.(see
menu: Mesh->Quadratic elements),
Maybe you can write linear elements with GiD, and increase the degree to
cubic inserting nodes inside your own code.

When I speak of volume connectivity I just want to say that the surface mesh 
elements which belong to a common face (a face shared between two solids)  
should include e reference to both adjiacient solids, that is to the 
geometrical parts of the CAD assembly (and not to the volume elements which 
are not needed).

There are two directions for the surface U and V.

  In V direction there are 3 points, 6 knots and the degree is 3
  In U direction there are 2 points, 4 knots and the degree is 2

The points (mark by the x) should be located like that:

    ----> U
    | |--------------------------|
    | |                          |
    | |    x        x        x   |
  V V |   1,1      2,1      3,1  |

      |    x        x        x   |
      |   1,2      2,2      3,2  |
      |                          |
      |--------------------------|

Using this scheme I do not understand the list of coordinates printed by
GiD: it looks like two points in the first (U) direction and three points
in the second (V) direction.

Could you please explain the GiD output.

Thanks a lot for your help.

The control points are like you said: and array of 3x2 points in u,v
directions
The u,v degrees are 2 and 1, not 3 an 2  (maybe you speak about the
order=degree+1)

Maybe the label "Point i,j" is confusing,  because the second index is
related to the u coordinate instead to the v

Notes:
- When you list a NURBS, if you double click on the line that show the
control point, this coordinate will be pointed
- When you use some tools, like divide surface, the u,v coordinate lines
will be temporary drawn.

Sorry, this was just a typing error.

Ok, that is important to know. I hope that the weights are in the same
order: second index = U running fastest, i.e.

  1,1
  1,2
  1,3
  2,1
  2,2
  2,3

Thanks a lot for your advice.

I would like to mesh a 3D geometry with unstructured hexahedral 
elements, I having problems because the program tells me that 
non-structured volume only can use tetrahedral elements. If it isn't 
possible, could you give me any advice?

Thanks and best regards!
(I have sent this e-mail to gidlist at cimne.upc.edu, so perhaps you will 
receive it twice, sorry)

It's like the message said:
GiD can't generate unstructured hexahedras, only can generate unstructured
volume tetrahedras.

Hexahedras can be obtained only for stuctured meshes, and also in last beta
versions for
semi-structured meshes (unstructured in two opposite surfaces, and
structured in an extrusion direction).

I don't know what's happening. 
Maybe it's some problem related with your problemtype tcl code?

Can you send your problemtype, and the steps to repeat this bug?
Which GiD version do you use?

  Subject: [GiDlist] problem in .dat

  Hi!

  After i introduce the values for each window menu's i save my problem type before going to another window.

  When i open .dat file, the results of *tcl command of .bas appears many times. 
  This only appens when i repeat this saves.
  When i save my project only at the end everything is ok.

  Do you know what is the problem?

  Thank you. I hope i make myself clear.

You used the checkbutton with a linked variable: -variable ::tkpoint::x
then this global variable store the current value, use
$::tkpoint::x

If you assign other value (like set ::tkpoint::x 1), the checkbutton will also reflect this result

  Subject: [GiDlist] Know if checkbutton is selected

    Hi!

  I have defined a checkbutton like this: 

    set c1 [checkbutton $parent.c1 -text "X:" -variable tkpoint::x ]

  proc ::tkpoint::setvarx { } {
    global ProblemTypePriv 
      variable x
      set x $value
      return ""
  }

  How can i get the value 0 or 1 (checkbutton selected or deselected)?
  If checkbutton is selected i introduce one value in a table; if is deselected i don't introduce nothing.

  It's possible to obtain that values? 

  $c1 *** ?

  Thank you.

Hello together,

I need your help for following "plotting"-problem:

Multi-material elements can have more than 1 material. In attached
illustration, a simple model with 3 elements, two materials has been
drawn.

1. Left element is filled (100%) with material 1.
2. Right element is filled (100%) with material 2.
3. Center element is mix-filled: 60% with material 1 and 40% with material 2.

I want to let GiD plot the center element in 2 colors as the
illustration shows. Some idea how to do that? Is it possible at all in
current GiD version (Linux: 7.7.2)?

As for the left and right element I do following:
1. I make a range table:
 - 0.0 - 1.0 : material 1
 - 10.0 - 11.0 : material 2
2. if f1 is equal 1.0 then fillingrate f = f1
    if f2 is equal 1.0 then fillingrate f = 10.0 + f2

I works well. Unfortunately for the center element does not.

Thank you in advance for any suggestion
Rafael
