[Gmsh] 3D Mesh not generated

[Lakshmi Selvakumaran]

Hi Matthias,

Thanks for your reply.  I was able to generate the mesh as well today
morning when I tried again.  But for some reason, when I save it, the mesh
file saves only the 2D mesh and not the 3D mesh.  Could you please tell me
what could be the problem?

Thanks.

Best regards
Lakshmi.
