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.
