#include "petscsnes.h" PetscErrorCode SNESNewtonTRSetPreCheck(SNES snes, PetscErrorCode (*func)(SNES,Vec,Vec,PetscBool*,void*),void *ctx)Logically Collective on snes
snes | - the nonlinear solver object | |
func | - [optional] function evaluation routine, see SNESNewtonTRPreCheck() for the calling sequence | |
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 SNESNEWTONTR solver.
