#include "petscksp.h" PetscErrorCode KSPSetCheckNormIteration(KSP ksp,PetscInt it)Logically Collective on KSP Many br
ksp | - Krylov solver context Many br | |
it | - use -1 to check at all iterations Many br |
Use KSPSetNormType(ksp,KSP_NORM_NONE) to never check the norm Many br
On steps where the norm is not computed, the previous norm is still in the variable, so if you run with, for example, Many br-ksp_monitor the residual norm will appear to be unchanged for several iterations (though it is not really unchanged). Many br Many br
