Hi,<br>
<br>
My code works when I use mumps option like<br>
-ksp_type preonly -pc_type lu -pc_factor_mat_solver_package mumps .<br>
<br>
But it does not work with -ksp_type preonly -pc_type lu -pc_factor_mat_solver_package superlu_dist <br>
It runs but cannot get anything. Are the options correct? Or the superlu_dist solver does not work with my matrix.<br></blockquote><div><br>Without any output, we have no idea what "cannot get anything" means. Run with -ksp_monitor -ksp_view -ksp_converged_reason<br>
and send the output.<br><br><br> Matt<br> </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
