Dear all, I modify the step-17 so that it uses PETScWrappers::SparseDirectMUMPS as solver. However, when I active the option of set_symmetric_mode, the solution has discrepancy from CG or MUMPS without the symmetry option. (The solutions from CG and MUMPS without symmetry option are identical though.) Any suggestion?
And it seems to me that PETScWrappers::SparseDirectMUMPS doesn't have the functionality of reusing the factorization of system matrix for different right-hand side vector. Do I miss anything? Thank you very much.
