KSPConvergedSkip#
Convergence test that do not return as converged until the maximum number of iterations is reached.
Synopsis#
#include "petscksp.h"
PetscErrorCode KSPConvergedSkip(KSP ksp, PetscInt n, PetscReal rnorm, KSPConvergedReason *reason, void *dummy)
Collective on ksp
Input Parameters#
ksp - iterative context
n - iteration number
rnorm - 2-norm residual value (may be estimated)
dummy - unused convergence context
Returns#
reason - KSP_CONVERGED_ITERATING, KSP_CONVERGED_ITS
Notes#
This should be used as the convergence test with the option KSPSetNormType(ksp,KSP_NORM_NONE), since norms of the residual are not computed. Convergence is then declared after the maximum number of iterations have been reached. Useful when one is using CG or BiCGStab as a smoother.
