[Gmsh] Extrude for unstructured mesh

[Mikhail Artemyev]

Hi Stephan,

I selected the outer surfaces as "Physical Surfaces", and it seems to 
work for me. Please, add this line at the end of your file and see if it 
works for you as well (as you know, you can replace 101 with whatever 
number you want to describe the outer surfaces).

Physical Surface(101) = { 13, 25, 37, 49, 10, 22, 34, 46 };

Best,
Mikhail
