PCCreate#
Creates a preconditioner context, PC
Synopsis#
#include "petscksp.h"
PetscErrorCode PCCreate(MPI_Comm comm, PC *newpc)
Collective
Input Parameter#
comm - MPI communicator
Output Parameter#
newpc - location to put the preconditioner context
Note#
The default preconditioner for sparse matrices is PCILU or PCICC with 0 fill on one process and block Jacobi (PCBJACOBI) with PCILU or PCICC
in parallel. For dense matrices it is always PCNONE.
