You can solve this problem by using the PETSc interface to MUMPS. See [this](https://community.freefem.org/t/install-parms-library-of-parallel-solvers/480/4) post, replace `-pc_type hypre` by `-pc_type lu` (though for simple problems such as heat equations and such, you should definitely use _hypre_ and not MUMPS).
