Hi Lulu, I saw a similar message from you on the moose-users list and just haven't had time to write a reply. Both of the DM interfaces in MOOSE and LibMesh were built by the same developer who has since moved to a new job. I'm not sure if either interface has been exercised much if at all since they were built. We just hired a new Petsc expert on the MOOSE team and he's planning on working on polishing up these interfaces as one of his first tasks. He's been in training all week so he probably hasn't seen your messages yet. I'll let him know that someone is asking about these interfaces in case he can answer your questions quickly.
