KSPSetUpOnBlocks#
Sets up the preconditioner for each block in the block Jacobi, overlapping Schwarz, and fieldsplit methods.
Synopsis#
#include "petscksp.h"
#include "petscmat.h"
PetscErrorCode KSPSetUpOnBlocks(KSP ksp)
Collective
Input Parameter#
ksp - the
KSP
context
Notes#
KSPSetUpOnBlocks()
is a routine that the user can optionally call for
more precise profiling (via -log_view) of the setup phase for these
block preconditioners. If the user does not call KSPSetUpOnBlocks()
,
it will automatically be called from within KSPSolve()
.
Calling KSPSetUpOnBlocks()
is the same as calling PCSetUpOnBlocks()
on the PC context within the KSP
context.
