[Gmsh] Converting 2d to 3d mesh

[Siming Bayer]

Dear Guillaume,

Thank you for your quick answer!

Well, I was able to generate a volumetric mesh from a .stl file. However,
the resulting .msh is quite large (90MB). Since I would like to do some
further FE analysis, I would like to reduce the size of the .msh file which
means the size of the 3D mesh elements should be increased. Is there any
command which specified the size of a mesh element? I have tried
Mesh.CharacteristicLengthMin, but it seems not work in my case. Is there
any examples for this scenario? Or any other commands?

And I also tried to use the command in the tutorial t13.geo. But my
gmsh.exe crashed while executing CreateTopology.

Any other ideas?

best,
Siming
