As mentioned to you twice already - mumps is a component of '-pc_type lu' so you need: -ksp_type preonly -pc_type lu -pc_factor_mat_solver_package mumps > As I understand it, this should read, no Krylov subspace method, no > preconditioner, use direct solver. '-pc_type lu' *IS* the direct solver in PETSc. There is no separate -directsolver category in PETSc. Satish
