Yeah - we know it causes problems with restart with solid mechanics for
instance.... because we might actually have some "penetration" of one part
of the mesh into another part of the mesh in a restart file... which causes
the global_indices to get assigned differently from how they were assigned
at the beginning of the simulation. That's a nasty problem.

Hmmm - I might be able to send it to you down the road. I'd have to double
check on that. It's actually not all that interesting though. A pretty
good approximation can be built from:
MeshTools::Generation::build_cube(mesh, 60, 256, 60, 0, 1, 0, 4, 0, 1);
It is being read in with the Exodus reader though.... and it does have
quite a few subdomains (I don't know if that matters).
Thanks for looking at this!
