PetscErrorCode KSPSetUpOnBlocks(KSP ksp)
Collective
Input Parameter#
ksp - the
KSPcontext
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.
