Dear All. Owing to good helper, I have gone through to initialize the PETScWrappers::MPI::BlockSparseMatrix type. However, maybe at this moment, deal.II can not support this type throughout all of area. Now I should use the MatrixTools::apply_boundary_values function for that matrix type, but, It does not work. Anyone have got through this problem? please give me a advice.
