KSPSkipConverged

Convergence test that NEVER returns as converged.

Synopsis

int KSPSkipConverged(KSP ksp,int n,double rnorm,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 KSPSetAvoidNorms(), 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.

Keywords

KSP, default, convergence, residual
