KSPSkipConverged

Convergence test that NEVER returns as converged.

Synopsis

#include "petscksp.h" 
int KSPSkipConverged(KSP ksp,int 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

0 -always

Notes

This is used as the convergence test with the option KSPSetNormType(ksp,KSP_NO_NORM), since norms of the residual are not computed. Convergence is then declared after a fixed number of iterations have been used. Useful when one is using CG or Bi-CG-stab as a smoother.
