Hi,I think `faceVariable` may be missing a `copy` method. I've included a patch below, which is basically a copy of `cellVariable`'s `copy` method (minus it's `hasOld` attribute and changing the rename from + '_old' to + '_copy').
Also, the patch includes a fix for matplotlib2DViewer.py, which has changed since I originally submitted the patch.
Cheers, -Tony

Description: Binary data
In case you're curious about a use case: I wanted to set *almost* all of the exterior faces to a no flux boundary condition. So I naturally I tried
>>> no_flux_faces = mesh.getExteriorFaces() >>> no_flux_faces.setValue(array[False], where=faces_with_other_BC)But it turns out the above commands change the faces that the mesh recognizes as exterior (`getExteriorFaces` doesn't automatically copy; for performance reasons, maybe?). So I just tried to copy before modifying:
>>> exterior = mesh.getExteriorFaces() >>> no_flux_faces = exterior.copy()But, `faceVariable`'s `copy` method defaults to `Variable`'s `copy` method. As a result, the copied variable doesn't have a `mesh` attribute.
