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#

pc - 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.
