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.
