# 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.
