Thanks! FYI, the only case where I recall definitely getting exponential convergence was on 1D problems with a "h refine only for elements next to predefined singularity points" heuristic. This suggests that we might have both a bug in the constraints generation and a bug or a poor design in the coarsening-based hp-selection heuristic. IIRC a while ago I identified a possible bug in the constraints generation but didn't have time to fix it. Let me see... http://www.mail-archive.com/[email protected]/msg01928.html And yes, that definitely looks like a bug. When we see high-p edge/face dofs on hanging nodes we're not constraining the right indices; we need to be testing FEInterface::extra_hanging_dofs and hitting the nodal dof indices in reverse order in that case. I can probably cook up a patch for that next week, but I don't have much time; would you be interested in helping test it? > I also owe you another PR on the user sensitivity routines for > sensitivity analysis.

I could swear I remember starting to look that over, but going back I can't find it in either the open or the closed pulls list on github. --- Roy ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
