[GiDlist] Node Numbering convention in GiD

[Enrique Escolano]

Note about the element conectivites:
The element can be located in any position in 3D (not necessary parallel to
xyz axis as in the pictures of the manual).

The normal of a quadrilateral is the same as the normal of the source
surface, check this normals
(the normals can be drawn and swapped)

By defaul in GiD, if a surface is created in a plane parallel to XY, then
your normal point automatically to the +Z axis,
and the local numeration of a quadrilateral generated 1 2 3 4 is
anti-clockwise.

hi,
the conectivities are the ones described in:

http://gid.cimne.com/support/gid_16.subst#cuad4.gif
http://gid.cimne.com/support/gid_16.subst#cuad8.gif
http://gid.cimne.com/support/gid_16.subst#cuad9.gif

you can also create a quadratic quadrilateral mesh
example in gid(pre), do a label all nodes and
list one of the elements (utilities-list-elements)
and you'll get the ordering of the nodes in gid.
i think this match with your description, or not?

Hi Guys
If any of you happened to know about node numbering
convention for element connectivity in GiD..especially
for 4 node and 8 node shell element..I'm still
confused with that..My previous FEM is such:

.s .s
2............1 2....5.....1
. . . . . .
. .........r 6. .....8...r
. . . .
3............4 3....7.....4
4 node 8 node
How we could make it satisfied with our own previous
Convention??

Thanks

Hi there
Thank Miguel for your reply. I'll try it as you
adviced,especially I have to look on TclTk part
deeply.

Another small thing I would like to ask again is:

in my Problemtype.bas file I used *CondNumEntities
to get number of nodes that assigned Loads on it. When
I assigned the different loads on the same one node
then I get number of Point load equals only 1. For
example, on node #53 I assigned Load Fx=10, Fy=20,
Mx=45,My=60 then my data file result is:
Number of Point Load = 1 (usually should be 4)
Node number Fx Fy Fz Mx My Mz
53 10 20 0 45 60 0
I try to use *set cond Point_Load *CanRepeat but I
didn't get the number of Laods equals 4.
How can we solve this problem?? I am sure that it
should be some command to deal with this??

Regards.

*condnumentities count the number of entities with an applied contition, and Fx, Fy, ... are fields of the same condition

Use an auxiliary loop to count the number of fields with not zero value
example: (for a condition named Point-Load, and fields named Fx, Fy, etc)

*set var cont=0
*set cond Point-Load *nodes *canrepeat
*loop nodes onlyincond
*if(cond(Fx,real)!=0)
*set var cont=operation(cont+1)
*endif
*if(cond(Fy,real)!=0)
*set var cont=operation(cont+1)
*endif
*if(cond(Fz,real)!=0)
*set var cont=operation(cont+1)
*endif
*if(cond(Mx,real)!=0)
*set var cont=operation(cont+1)
*endif
*if(cond(My,real)!=0)
*set var cont=operation(cont+1)
*endif
*if(cond(Mz,real)!=0)
*set var cont=operation(cont+1)
*endif
*end nodes
Nº total= *cont

Hi Enrique
Thanks so much for your immediate reply. I got
ideas from your advice and I'll apply to other
problems too.
Many thanks..

Hello,

Check options:

CANREPEAT: yes

in .cnd file

and *CanRepeat in .bas file

Hi there
Please give your advice!!!
I'm working on "Pressure Load" for Solid element.
How can we have GiD to select the Face of the solid
element??is there any possibility? in my file .cnd, I
used
CONDTYPE:over surfaces
but when selecting the element it was selected as a
whole element not a surface (or face of element). How
we deal with this kinda problem?

Best regards.

Hi all GiDs
I have problem with GiD.7 when trying to write the
CalFile. I have no problem when using with GiD6.2 but
when transferring my ProblemType to GiD.7 I noticed
that so many options included.
In problemType_name.mat, in GiD.7 allows only 100
fields. Actually my fields (QUESTION:) are more than
100. My question is:
1. Do you have any option to ovoid this limitation?
2. In case I have more fields in this
ProblemType_name.mat file. Can GiD allow to have more
than 1 file of ProblemType_name.mat file?
3. If not from two listed above how should we solve
this problem?

Best regards.

Hi GiD Team
I transferred my ProblemType_name.gid to GiD.7 but
in this version it said that Too many fields in mat
file, 100 fields are limited.Then some fields are not
recognized when writing the .bas file? I use Pro
Version and still got the same problem.

Why? there should be some limitation?

Regards
