[Gmsh] structured mesh in wedge.

[mark starnes]

Hi everyone.  I've spent a couple of days trying to crack this one and 
now have to admit to needing help.  I have a wedge I'd like to mesh 
using a structured mesh.  Following example 6,  I defined my lines with 
the same directions, my surfaces with the same normals, my transfinite 
surfaces with the same topology order and my transfinite volume with the 
same topology order.  The surface elements are displayed but the 3D 
elements will not generate.  If somebody can let me know what I'm doing 
wrong, I'd appreciate it.

Regards,

Mark Starnes.
