Dear Daniel,
Thank you a lot for the solution ways! I was trying to modify the
/dealii-9.3.1/source/numerics/matrix_tools.inst.in as follows:
// ---------------------------------------------------------------------

for (number : REAL_SCALARS)
{
template void MatrixTools::local_apply_boundary_values(
const std::map<types::global_dof_index, number> &boundary_values,
const std::vector<types::global_dof_index> & local_dof_indices,
FullMatrix<number> & local_matrix,
Vector<number> & local_rhs,
const bool eliminate_columns);
template void MatrixTools::apply_boundary_values(
const std::map<types::global_dof_index, number> &boundary_values,
SparseMatrix<number> & matrix,
Vector<number> & solution,
Vector<number> & right_hand_side,
const bool eliminate_columns);
template void MatrixTools::apply_boundary_values(
const std::map<types::global_dof_index, number> &boundary_values,
BlockSparseMatrix<number> & matrix,
BlockVector<number> & solution,
BlockVector<number> & right_hand_side,
const bool eliminate_columns);
}
for (number : COMPLEX_SCALARS)
{
template void MatrixTools::apply_boundary_values(
const std::map<types::global_dof_index, number> &boundary_values,
SparseMatrix<number> & matrix,
Vector<number> & solution,
Vector<number> & right_hand_side,
const bool eliminate_columns);
*template void MatrixTools::apply_boundary_values(*
* const std::map<types::global_dof_index, number> &boundary_values,*
* BlockSparseMatrix<number> & matrix,*
* BlockVector<number> & solution,*
* BlockVector<number> & right_hand_side,*
* const bool eliminate_columns);*
}
Then I recompiled everything and got the error:
/home/mariia/Downloads/dealii-9.3.1/source/numerics/matrix_tools.cc:364:49:
*error*: no match for ‘operator!=’ (operand types are ‘std::complex<float>’
and ‘double’)
364 | .diag_element(block_index.second) != 0.0)

I am a bit confused, what else needs to be adjusted may be in the
matrix_tools.cc. I would greatly appreciate help here.
Thank you for your time!
With kind regards,
