Hello,<br>
<br>
I would like to use SuperLU as a direct solver for a large size problem running on multiple processors.<br>
<br>
I have write the analytical Jacobian via FormJacobianLocal(), however, I do not know how to set the direct solver.<br>
<br>
Any thoughts?<br></blockquote><div><br></div><div>You need SuperlU_Dist:</div><div><br></div><div>-ksp_type preonly -pc_type lu -pc_factor_mat_solver_package superlu_dist</div><div><br></div><div> Matt</div><div> </div>
