Dear Gmsh users, I have a small question about how GMSH extrudes a meshed surface. The script I have attached to the email, creates a cylindrical tube extruding one of the two flat borders in the z direction. The mesh of the extruded border is structured and symmetric w.r.t the line x=y (the straight line of 45 degrees). When I extrude the mesh, the two curved surfaces I get are almost structured. There are some elements (placed in random position?) which make the mesh non completely structured.
Why this? I would need a structured mesh and not an almost structured mesh. Is that possible to have the two curved surfaces structured? Many thanks for any suggestion, Paolo
