Ok, I don't know what changed, but I reinstalled literally everything on my
system. Python, fipy, gmsh, etc. It seems, for the moment that gmsh 2.11 is
reading now. I'm still getting the error about not producing any cells.
To answer your questions, I'm running Windows 7 Professional.
Running gmsh --version at the command line gets me Gmsh 2.11.0
Here's the errors from running the circle example:
Exception WindowsError: (32, 'The process cannot access the file because it
is being used by another process',
'c:\\users\\ddesan~1\\appdata\\local\\temp\\tmpzs_8ji.msh') in <bound
method MSHFile.__del__ of <fipy.meshes.gmshMesh.MSHFile instance at
