Dear All,
In my work, I am employing with PETScWrappers::MPI::BlockSparseMatrix. Due to computation time, I must do with AMR. Unluckily, For deal.II lib. can not make it with between "PETScWrappers::MPI::BlockSparseMatrix/Vector" and "MatrixTools::apply_boundary_values function". Even if I can use the function MatrixTools::local_apply_boundary_values, this function can not guarantee a good job with hanging nodes along the boundary nodes. Question: Why can not make a code "MatrixTools::apply_boundary_values function" for PETScWrappers::MPI::BlockSparseMatrix data type? Why is that difficult to make this code? I found there exists code for BlockSparseMatrix and also PETScWrappers::MPI::SparseMatrix. Could you give a clue of understanding? If possible, I would modify inside code of deal.II, because of urgent stuffs I must go through. Thank you. Sungho Yoon Leeds UK _______________________________________________
