I am pretty sure that this is related to the following problem: When I try to run AMR with this FESystem (Nedelec-RaviartThomas-DGQ) with more than one MPI rank I get this error
"An error occurred in line <1626> of file </home/ksimon/lib/dealii-9.2.0-src/include/deal.II/lac/affine_constraints.h> in function void dealii::AffineConstraints<number>::add_line(dealii::AffineConstraints<number>::size_type) [with number = double; dealii::AffineConstraints<number>::size_type = unsigned int] The violated condition was: line_n != numbers::invalid_size_type Additional information: This exception -- which is used in many places in the library -- usually indicates that some condition which the author of the code thought must be satisfied at a certain point in an algorithm, is not fulfilled. An example would be that the first part of an algorithm sorts elements of an array in ascending order, and a second part of the algorithm later encounters an element that is not larger than the previous one. There is usually not very much you can do if you encounter such an exception since it indicates an error in deal.II, not in your own program. Try to come up with the smallest possible program that still demonstrates the error and contact the deal.II mailing lists with it to obtain help. " which is thrown in AffineConstraints::add_line <https://dealii.org/current/doxygen/deal.II/affine__constraints_8h_source.html#l01618> (see the second assert in line 1826) after being called by make_hanging_node_constraints. It seems that deal.ii is trying to setup constraints on dofs that are not owned by the MPI process. I read a little bit in the discussions referring to Nedelec and refinement - seems a difficult issue. Did anyone run into this, too?
