[Gmsh] Wall-mounted Cube!

[Ruth V. Sabariego]

Hi Daniel,
If you want to keep quadrangles as boundary of your cube, you should use
Layers and Recombine when you extrude. Your mesh will be then fully
structured.

Other possibility for getting the 3D mesh would be not recombining the
faces of your cube and just extrude as you've done in your file.
In that case, you must use Netgen for meshing. You can just add:
Mesh.Algorithm3D = 4;
to your file.
Regards,
Ruth
