This is really a question for Ben. I remember some discussion about
pyramids... but I'm not sure they can be refined at all by libMesh
(because of not being self-similar). But I don't know for sure.
I think John did most of the pyramid work, and IIRC it does work - the
five corner children are pyramids (and similar to the parent since we
only support 1st order pyramids) but I believe there's an inverted
sixth pyramid and some tets in the middle. The really weird bit is
the rational (non-polynomial!) basis functions, but that won't be an
issue for fixing a topology-based method.
Tim Kroger did the diagonal selection work. I think I can figure that
out on my own but I'll try picking his brains if I fail. He hasn't
(yet?) been snatched up by your "hire all the best libMesh developers
you can" plan, but he's still active on the lists as of a few weeks
ago. ;-)
