SNESConvergenceTestFunction

functional form used for testing of convergence of nonlinear solver

Synopsis

#include "petscsnes.h"
$     PetscErrorCode SNESConvergenceTest(SNES snes,PetscInt it,PetscReal xnorm,PetscReal gnorm,PetscReal f,SNESConvergedReason *reason,void *cctx)
snes - the SNES context
it - current iteration (0 is the first and is before any Newton step)
cctx - [optional] convergence context
reason - reason for convergence/divergence
xnorm - 2-norm of current iterate
gnorm - 2-norm of current step
f - 2-norm of function
