SNESNewtonTRDCPostCheck#

Called after the step has been determined in SNESNEWTONTRDC but before the function evaluation at that step

Synopsis#

#include "petscsnes.h"   
static PetscErrorCode SNESNewtonTRDCPostCheck(SNES snes, Vec X, Vec Y, Vec W, PetscBool *changed_Y, PetscBool *changed_W)

Logically Collective

Input Parameters#

  • snes - the solver

  • X - The last solution

  • Y - The full step direction

  • W - The updated solution, W = X - Y

Output Parameters#

  • changed_Y - indicator if step has been changed

  • changed_W - Indicator if the new candidate solution W has been changed.

Note#

If Y is changed then W is recomputed as X - Y
