SNESNewtonTRSetPostCheck#
Sets a user function that is called after the search step has been determined but before the next function evaluation. Allows the user a chance to change or override the internal decision of the solver
Synopsis#
#include "petscsnes.h"
PetscErrorCode SNESNewtonTRSetPostCheck(SNES snes, PetscErrorCode (*func)(SNES, Vec, Vec, Vec, PetscBool *, PetscBool *, void *), void *ctx)
Logically Collective
Input Parameters#
snes - the nonlinear solver object
func - [optional] function evaluation routine, for the calling sequence see
SNESNewtonTRPostCheck()ctx - [optional] user-defined context for private data for the function evaluation routine (may be
NULL)
Note#
This function is called BEFORE the function evaluation within the solver while the function set in
SNESLineSearchSetPostCheck() is called AFTER the function evaluation.
