[ GiDlist ] Triangular element

[Nguyen, Binh]

Hi;

I have had trouble in generating mesh on a surface. I realised that in order
to generate triangular elements (instead of tetrahedra by default), the
surface has to be structured.
Anyway, I'm wondering if I could produce a triangular mesh surface on a
sphere or a cylinder or any enclosed volumes.

If I have understood your question, you are asking about the generation of a
surface mesh.
If yes, you have just to indicate 'no mesh' for the volumes and 'mesh' for
the surfaces.
In the case of a sphere, you can test the next example:

geometry create Object Sphere
0,0,0
2
zoom frame
escape
escape
Meshing
MeshCriteria
NoMesh
Volumes
1
escape
MeshCriteria
Mesh
Surfaces
1 2 3 4
escape
Generate
0.64

J

In addition to my last message, you can find the 'mesh' commands in the
following menu:

Meshing - Mesh Criteria - No Mesh - Volumnes (and you have to select the
volumes)

Meshing - Mesh Criteria - Mesh - surfaces (and you have to select the
surfaces)
