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