Note that one can specify in-place ILU(0) factorization by calling Many br
PCType(pc,PCILU); PCFactorSeUseInPlace(pc);Many bror by using the options -pc_type ilu -pc_factor_in_place Many br
In-place factorization ILU(0) can also be used as a local Many brsolver for the blocks within the block Jacobi or additive Schwarz Many brmethods (runtime option: -sub_pc_factor_in_place). See Users-Manual: ch_pc Many brfor details on setting local solver options. Many br
Most users should employ the simplified KSP interface for linear solvers Many brinstead of working directly with matrix algebra routines such as this. Many brSee, e.g., KSPCreate(). Many br
