this is the default used by fgmres - it doesn’t change the preconditioner.
Synopsis#
#include "petscksp.h"
PetscErrorCode KSPFGMRESModifyPCNoChange(KSP ksp, PetscInt total_its, PetscInt loc_its, PetscReal res_norm, void *dummy)
Input Parameters#
ksp - the ksp context being used.
total_its - the total number of FGMRES iterations that have occurred.
loc_its - the number of FGMRES iterations since last restart. a restart (so number of Krylov directions to be computed)
res_norm - the current residual norm.
