Hello Wolfgang, Ok, good. The commit is fine. I'll see if I can pinpoint the exact cause of segmentation faults. One more question, in fact a small inconsistency that is of my interest: the function VectorTools::interpolate_boundary_values is not templated for the generic Number type but for double only (argument std::map<types::global_dof_index,double>& boundary_values). Is there a reason for that?
