Sorry this took me a while.

You are right, I have not implemented the 3D version yet. It is
straightforward, but in the paper there are 96 cases. I would like
to automatically generate that, but I need to figure out how that would go.
Right now all the adaptation requests have been for
2D, or used ParMMG which works in 3D for PETSc right now.

  Thanks,
