WebCommon reasons for KSP not converging The equations are singular by accident (e.g. forgot to impose boundary conditions). Check this for a small problem using -pc_type svd -pc_svd_monitor. Also try a direct solver with -pc_type lu (via a third-party package in parallel, e.g. -pc_type lu -pc_factor_mat_solver_package superlu_dist ).
