Convergence test for SNES that NEVER returns as converged, UNLESS the maximum number of iteration have been reached.
Synopsis
#include "petsc/private/snesimpl.h"
PetscErrorCode SNESConvergedSkip(SNES snes,PetscInt it,PetscReal xnorm,PetscReal snorm,PetscReal fnorm,SNESConvergedReason *reason,void *dummy)
Logically Collective on SNES
Input Parameters
| snes | - the SNES context
|
| it | - the iteration (0 indicates before any Newton steps)
|
| xnorm | - 2-norm of current iterate
|
| snorm | - 2-norm of current step
|
| fnorm | - 2-norm of function at current iterate
|
| dummy | - unused context
|
