Maybe I'm missing the point here (as a total noob I would not be
surprised if this were the case) but if I just mesh what you sent in
Mesh/2D I get a mixture of quads and tris. Screen grab attached. If I
look in the file you sent it says
Mesh.SubdivisionAlgorithm=2;
This thread also was interesting for me.
If you check the file there are some comments, actually the 2 option is
for all hexas as mentioned there, if you use option 1 that is what you
want to get even if there are some error messages.
