Extruded mesh in available volume
It’s a pitty to create a tet mesh since a 2D mesh could be extruded to create a hex mesh. What would be the way to script this for the general case of a metal sheet with any contour?
From the manual, I understand that one starts with a 2D mesh and then extrudes it to a 3D hex mesh. So the volume is created after mesh extrusion. But what if the volume is already there?
- Can I specify the starting and ending surfaces and let GMSH extrude the mesh?
- Or maybe 2D mesh both starting and ending surfaces and tell GMSH to map the 3D mesh between the 2D meshes?
The second case would be more general I think, since it could be that the extrusion direction is not always perpendicular to the starting an ending surfaces.
