Hello Daniel, thanks for the observations. Interesting that the problem doesn't depend on the hp framework. I myself managed to debug the problem a little bit further with gdb on the second running process (when starting with -np 2) and got the following backtrace directly before crashing: >>>

Mathias, some observations: - it seems that the call to nonlocal_graph->FillComplete (https://github.com/dealii/dealii/blob/master/source/lac/trilinos_sparsity_pattern.cc#L820) is failing for block (0,1). - the code also fails for me when using a DoFHandler object instead of a hp::DoFHandler o

Hello, I want to use the deal.II hp::DoFHandler in a principally similar way as in step-46 - so using it with a coupled problem. I'm at the beginning of implementing this and want to use deal.II with Trilinos, so that the program can run on distributed machines. Unfortunately I have a problem wh
