Select in the window this "rigth buttons" inside.

Then from this buttons, you can set this variables with
Utilities Variables, then you can see the available GiD variables

In fact, it's not necessary to visualise this buttons, you can write the commands in the lower command line, e.g, can write
escape escape escape utilities variables AlignSemiStructuredNodes 1

Hi!

Thanks for your reply. I answer through your e-mail:

I think that we didn't understand your meaning of "irregularities in the mesh"
I think that you don't want to say "elements with bad angles or sizes", and what you want
is that all extruded nodes have exactly the same XY proyection. Is not?

Yes, you are right. I meant just what you have described.
Structured or semi-structured meshes will not generate aligned-like nodes in the extrusion direction, the algorithm is not a
simple
translation, is more general (lateral surfaces can be curved, and both tops must have the same number of boundaries, but can
have
different shape)

Last 8.1.x beta versions have an "special option" to try to force this alignement if possible, by setting the GiD variable
AlignSemiStructuredNodes to 1
escape escape escape utilities variables AlignSemiStructuredNodes 1
(but your 8.0.8 official version doesn't has this option)

Then, I have just downloaded Gid8.1.2b-win-x32.exe, which is a beta
version but I am not able to find the GiD variable
AlignSemiStructuredNodes and to put it to 1.
Could you say to me where it is exactly?
Thanks in advance and best regards
Isa

Next week we are releasing a new beta version 8.1.3 that also has a new unstructured quadrilateral meshing algorithm,
Obtained quadrilaterals will have much better shape quality. Can set this mesher with the variable:
escape escape escape utilities variables QuadrilateralMesher 1

Hello!

First of all, thanks for your reply.

Your are right with the so different size of mesh elements I am using,
but if you, in the previous project I sent you, put "RENDER-normal" and
put on and off the "layer capa2_a", you can see that different lines
appear (you can see this effect at first sight on the left at the bottom
with only the "layer capa1_a" on and putting the "layer capa2_a" on and
off, with the view of XY plane).
Do you mean that these irregularities in the mesh is due to my bad size
election?

Again, thank-you very much in advance.

Best regards!
Isa

Hi,

If you mean that the elements are quite distorted, i think it's because you
have assigned element size of '2' for some volumes (layers 'capa1_a' and
'capa1_b' with a height of 0.002) and '4' for others (layers 'capa2_a' and
'capa2_b' with a height of 0.002). Some details of the surfaces conforming
the volumes is just 0.001. You can see it at 'ig_volume_size_1.png'.

And, for instance, at the layer 'capa1_b', there are surfaces with element
size assigned of 0.0059 (and the width of the surface is just 0.002) and
just beside them surfaces with element size of 0.000325, 15 times less, as
you can see in the image 'ig_surface_size_1.png', resulting in the mesh
shown in 'ig_mesh_zoom_1.png'.
Best regards,

Miguel

Asunto: [GiDlist] Semistructured volume

Hello GiD'users!

I have a little problem when I want to create a mesh.
I am working with GID 8.0.8 in Windows.


I attach my project because I don't get to make a good semistructured
volume with structured mesh
in z-direction. You can see the irregularities of the mesh if you use
the XY-plane view and the rotate trackball tool.

I don't know what I am doing wrong. I think I followed correctly the
advice that previous e-mails
gave me but perhaps I am forgetting something.

I would be really grateful if you could cast a glance at it.

Thanks in advance and best regards
Isa
