KSPSetUpOnBlocks
Sets up the preconditioner for each block in the block Jacobi, block Gauss-Seidel, and overlapping Schwarz methods.
Synopsis
#include "petscksp.h"
PetscErrorCode KSPSetUpOnBlocks(KSP ksp)
Collective on ksp
Input Parameter
ksp -the KSP context
Notes
KSPSetUpOnBlocks() is a routine that the user can optinally 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.
