PCSetUpOnBlocks#
Sets up the preconditioner for each block in the block Jacobi, overlapping Schwarz, and fieldsplit methods.
Synopsis#
#include "petscksp.h"
PetscErrorCode PCSetUpOnBlocks(PC pc)
Collective
Input Parameter#
pc - the preconditioner context
Notes#
For nested preconditioners such as PCBJACOBI, PCSetUp() is not called on each sub-KSP when PCSetUp() is
called on the outer PC, this routine ensures it is called.
It calls PCSetUp() if not yet called.
