Hi everybody!
I have the following question to ask:
I have two different layers in 3D (both of them belong of the same
geometry and sharing the plane XY) and I would like to use a
semistructured mesh:
- On one of the layers I would like to have a semistructured mesh in XY
plane and 4 divisions in structured direction (Z).
- On the another one I would like to have the same semistructured mesh
in XY plane but 10 divisions in structured direction (Z).
How would the way be in order to get this aim?
Any advice will be welcome.
Best regards and thanks in advance!

Dear Isa,
When you select a volume as Semi-structured, a window comes asking for the
number of divisions in the structured direction, and you can assign a
different number of divisions to different volumes.

ABEL

Thanks Abel,
The problem isn't in the structured direction, it is in the plane where
the elements are unstructured.
Let's imagine I have a cube with 2 divisions in the structured direction
(z-axis) and 10 divisions per lines that form a square in the XY-plane.
I have the mesh created.
Later, I create another cube (on another layer) and I want to have
different divisions in the structured direction (z-axis), what I get it
easily, and I also want to have the same mesh in the XY-plane that both
cubes share, how could I do this last one?
Thanks in advance and best regards

[GiDlist] Two layers, same mesh in plane XY, different divis
I don't understand well your questions.
Do you have two volumes in two different places, or they have some surface in the same location? Then they share this surface?
If a surface is shared between two volumes, then its nodes are also shared. Maybe you need to collapse both surfaces.
If they are two separated surfaces, in general unstructured meshes obtained can be different.
You can force the number of divisions in lines with Mesh-Structured-Lines
If you really need to have the "same mesh" (a one-by-one relationship between nodes), you can do a trick: create a "separated
contact volume" between this two surfaces (Geometry-Create-Contact-Separated volume).
By default this pseudo-volume will create prisms connecting nodes, but you can avoid to create elemens for this volume with
Mesh-Mesh criteria-No mesh-Volumes

Sorry for my explanation.
I will try to clarify my doubts.
I have two volumes (indeed two cubes) in different layers that share one
surface.
Volume1 is already meshed and I would like to extrude its mesh made in
the sharing surface (XY-plane) into the opposite face of the Volume2.
On the other hand, I can have different divisions on the structured
direction in each volume, which is a feature that I need.
I have tried to use "Geometry-Create-Contact-Separated volume", as you
said (without using Geometry-Collapse-Model) but the message I obtain is
"2 surfaces are necessary".
Thanks in advance and best regards

Thanks Abel,
The problem isn't in the structured direction, it is in the plane where
the elements are unstructured.
Let's imagine I have a cube with 2 divisions in the structured direction
(z-axis) and 10 divisions per lines that form a square in the XY-plane.
I have the mesh created.
Later, I create another cube (on another layer) and I want to have
different divisions in the structured direction (z-axis), what I get it
easily, and I also want to have the same mesh in the XY-plane that both
cubes share, how could I do this last one?
Thanks in advance and best regards

Asunto: [GiDlist] Two layers, same mesh in plane XY, different division in X
axis.
Hi everybody!
I have the following question to ask:
I have two different layers in 3D (both of them belong of the same
geometry and sharing the plane XY) and I would like to use a
semistructured mesh:
- On one of the layers I would like to have a semistructured mesh in XY
plane and 4 divisions in structured direction (Z).
- On the another one I would like to have the same semistructured mesh
in XY plane but 10 divisions in structured direction (Z).
How would the way be in order to get this aim?
Any advice will be welcome.
Best regards and thanks in advance!
Isa

[GiDlist] Two layers, same mesh in plane XY, different divis
Hello,
Let's see if i've understood you:
¿you want something like the pictures I send you enclosed:
'Semistructured2cubes.png' and 'Semistructured2cubes2.png'?
To achieve this I've followed these steps:
Creation of the geometry: a square in the xy plane, and then an extrusion
with rotation of 60 degrees on the positive (in one layer) and negative Z
axis (in the other layer).
Semistructured mesh:
1. I choose 'Mesh--semistructured--Volumes' and a windows pop's up asking
me 'Enter number of divisions and assign it to the semi-structured volumes'.
2. I entered '4' and clicked on one volume,
3. then I entered '10' and clicked on the other volume.
4. then I pressed 'escape'.
5. now I chose 'Mesh--semistructured--Set--Master surface'
6. and selected the square which lies on the XY plane, because the mesh of
this 'master surface' will be the one to be extruded along the volumes,
i.e., the z axis.
7. and generated the mesh (Ctrl-G): 1260 Prisms.
I send you enclosed the model, too.
If this is not want you need, ¿can you send us an example?
Miguel

Asunto: Re: [GiDlist] Two layers, same mesh in plane XY, different division
in X axis.
Sorry for my explanation.
I will try to clarify my doubts.
I have two volumes (indeed two cubes) in different layers that share one
surface.
Volume1 is already meshed and I would like to extrude its mesh made in
the sharing surface (XY-plane) into the opposite face of the Volume2.
On the other hand, I can have different divisions on the structured
direction in each volume, which is a feature that I need.
I have tried to use "Geometry-Create-Contact-Separated volume", as you
said (without using Geometry-Collapse-Model) but the message I obtain is
"2 surfaces are necessary".
Thanks in advance and best regards

I don't understand well your questions.
Do you have two volumes in two different places, or they have some surface
in the same location? Then they share this surface?
If a surface is shared between two volumes, then its nodes are also
shared. Maybe you need to collapse both surfaces.
If they are two separated surfaces, in general unstructured meshes
obtained can be different.
You can force the number of divisions in lines with
Mesh-Structured-Lines
If you really need to have the "same mesh" (a one-by-one relationship
between nodes), you can do a trick: create a "separated
contact volume" between this two surfaces
(Geometry-Create-Contact-Separated volume).
By default this pseudo-volume will create prisms connecting nodes, but you

[GiDlist] Two layers, same mesh in plane XY, different divis
Thank-you very much. Your plots have helped a lot.
Yes, more or less it is your problem which I was asking about.
Other questions that have sprung up are the following ones:
- Do you collapse the model? I mean, do use
"Geometry-edit-collapse-model" (or "Geometry-edit-collapse-surfaces" or
"Geometry-edit-collapse-volume") before using semistructured mesh? If
you do, which one, among these three possibilities, do you use?
- I have the same problem as you have but, in my case, the geometry that
lies on the layer (number 1) is already meshed (and although I speak of
cube, the geometry I actually use is more complicated). Then, I create
the second cube on another layer (number 2) but I would like to have the
same mesh on the master surface as you have. The only difference is that
the mesh over one cube is created previously.
Perhaps, the only solution is to create all mesh together from scratch
every time I add a new piece of my geometry. However, I have to create
and simulate my mesh little by little and if I have to create the
entirely mesh every time, it is really hard stuff, isn't it?
I don't know if I have explain myself correctly.
Again, thanks very much. I am looking forward to hearing from you.

Asunto: Re: [GiDlist] Two layers, same mesh in plane XY, different division
in X axis.
Sorry for my explanation.
I will try to clarify my doubts.
I have two volumes (indeed two cubes) in different layers that share one
surface.
Volume1 is already meshed and I would like to extrude its mesh made in
the sharing surface (XY-plane) into the opposite face of the Volume2.
On the other hand, I can have different divisions on the structured
direction in each volume, which is a feature that I need.
I have tried to use "Geometry-Create-Contact-Separated volume", as you
said (without using Geometry-Collapse-Model) but the message I obtain is
"2 surfaces are necessary".
Thanks in advance and best regards

I don't understand well your questions.
Do you have two volumes in two different places, or they have some surface
in the same location? Then they share this surface?
If a surface is shared between two volumes, then its nodes are also
shared. Maybe you need to collapse both surfaces.
If they are two separated surfaces, in general unstructured meshes
obtained can be different.
You can force the number of divisions in lines with
Mesh-Structured-Lines
If you really need to have the "same mesh" (a one-by-one relationship
between nodes), you can do a trick: create a "separated
contact volume" between this two surfaces
(Geometry-Create-Contact-Separated volume).
By default this pseudo-volume will create prisms connecting nodes, but you
can avoid to create elemens for this volume with
Mesh-Mesh criteria-No mesh-Volumes

Thanks Abel,
The problem isn't in the structured direction, it is in the plane where
the elements are unstructured.
Let's imagine I have a cube with 2 divisions in the structured direction
(z-axis) and 10 divisions per lines that form a square in the XY-plane.
I have the mesh created.
Later, I create another cube (on another layer) and I want to have
different divisions in the structured direction (z-axis), what I get it
easily, and I also want to have the same mesh in the XY-plane that both
cubes share, how could I do this last one?
Thanks in advance and best regards

Asunto: [GiDlist] Two layers, same mesh in plane XY, different division
in X
axis.
Hi everybody!
I have the following question to ask:
I have two different layers in 3D (both of them belong of the same
geometry and sharing the plane XY) and I would like to use a
semistructured mesh:
- On one of the layers I would like to have a semistructured mesh in XY
plane and 4 divisions in structured direction (Z).
- On the another one I would like to have the same semistructured mesh
in XY plane but 10 divisions in structured direction (Z).
How would the way be in order to get this aim?
Any advice will be welcome.
Best regards and thanks in advance!
Isa

[GiDlist] Two layers, same mesh in plane XY, different divis
1 - Collapse is a tool to join "near entities" (near with a small tolerance, you can set it from preferences - Import tolerance).
Probably in your case the result of collapse model, volume, or only selecting the overlapped surfaces will be the same.
- collapse model try to collapse all without ask for selection
- collapse volumes will try to collapse the selected volumes and its dependencies (surfaces, lines, points)
- collpase surfaces will try to collapse the selected surfaces and its dependencies (lines, points)
2- You must mesh all togheter, in general with GiD can't create a mesh part by part.
All direct operations over mesh are unrecommended, it's better to do operations only with the geometry,
and then generate automatically the final mesh.
You can set some entities to not be meshed, with Mesh-Mesh criteria-No mesh-...
this is usual for meshing tests, or simulate only some part without delete other parts, etc.
but to have the final complete mesh, you must remesh all togheter.

Subject: Re: [GiDlist] Two layers, same mesh in plane XY, different division in X axis.
Thank-you very much. Your plots have helped a lot.
Yes, more or less it is your problem which I was asking about.
Other questions that have sprung up are the following ones:
- Do you collapse the model? I mean, do use
"Geometry-edit-collapse-model" (or "Geometry-edit-collapse-surfaces" or
"Geometry-edit-collapse-volume") before using semistructured mesh? If
you do, which one, among these three possibilities, do you use?
- I have the same problem as you have but, in my case, the geometry that
lies on the layer (number 1) is already meshed (and although I speak of
cube, the geometry I actually use is more complicated). Then, I create
the second cube on another layer (number 2) but I would like to have the
same mesh on the master surface as you have. The only difference is that
the mesh over one cube is created previously.
Perhaps, the only solution is to create all mesh together from scratch
every time I add a new piece of my geometry. However, I have to create
and simulate my mesh little by little and if I have to create the
entirely mesh every time, it is really hard stuff, isn't it?
I don't know if I have explain myself correctly.
Again, thanks very much. I am looking forward to hearing from you.
Best regards

Hello,
Let's see if i've understood you:
¿you want something like the pictures I send you enclosed:
'Semistructured2cubes.png' and 'Semistructured2cubes2.png'?
To achieve this I've followed these steps:
Creation of the geometry: a square in the xy plane, and then an extrusion
with rotation of 60 degrees on the positive (in one layer) and negative Z
axis (in the other layer).
Semistructured mesh:
1. I choose 'Mesh--semistructured--Volumes' and a windows pop's up asking
me 'Enter number of divisions and assign it to the semi-structured volumes'.
2. I entered '4' and clicked on one volume,
3. then I entered '10' and clicked on the other volume.
4. then I pressed 'escape'.
5. now I chose 'Mesh--semistructured--Set--Master surface'
6. and selected the square which lies on the XY plane, because the mesh of
this 'master surface' will be the one to be extruded along the volumes,
i.e., the z axis.
7. and generated the mesh (Ctrl-G): 1260 Prisms.
I send you enclosed the model, too.
If this is not want you need, ¿can you send us an example?

Hi
I am trying to generate quadratic hexahedral mesh in a simple cube. I am
not able to understand the numbering sequence of the nodes. Should it not
be like what is described in the documentation viz. all corners first and
then the middle points ?
I have enclosed the screen print of the cube as jpg file. To understand, I
have generated one element.
Can anyone help me?
