I've been using subdomain-only variables for a conjugate heat transfer problem and I wanted to introduce some mesh refinement "by hand" by marking some specific elements for refinement. Doing this, though, appears to corrupt the system assembly (as evidenced by non-convergence of Newton iterations). The issue appears to be independent of which elements I mark for refinement. Also, if I do a global uniform refinement then everything works fine. So I wonder if there might be a problem with the hanging node constraints for subdomain-only variables?
I'd be happy to prepare a test case, but thought I'd run this by the list first to see if anyone has any thoughts/suggestions.
