Sets the function that is to be used to test for convergence of the nonlinear iterative solution.

Synopsis

#include "petscsnes.h"  
PetscErrorCode SNESSetConvergenceTest(SNES snes, PetscErrorCode (*SNESConvergenceTestFunction)(SNES, PetscInt, PetscReal, PetscReal, PetscReal, SNESConvergedReason *, void *), void *cctx, PetscErrorCode (*destroy)(void *))

Input Parameters

• snes - the SNES context

• SNESConvergenceTestFunction - routine to test for convergence

• cctx - [optional] context for private data for the convergence routine (may be NULL)
