[Gmsh] Not getting a volume mesh

[Wayne Christopher]

Hi Ruth,

Thanks - that fixes my volume problem.

My other problem remains, though.  I want to define geometry using a msh 
file, and then create a mesh with new surface elements, not the ones I 
am using for geometry surfaces.    Is there a way to do this?
