SNESNewtonTRGetPostCheck#

Gets the post-check function

Synopsis#

#include "petscsnes.h"   
PetscErrorCode SNESNewtonTRGetPostCheck(SNES snes, PetscErrorCode (**func)(SNES snes, Vec X, Vec Y, Vec W, PetscBool *changed_Y, PetscBool *changed_W, PetscCtx ctx), PetscCtxRt ctx)

Not Collective

Input Parameter#

  • snes - the nonlinear solver context

Output Parameters#

  • 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)

Calling sequence of func#

  • snes - the nonlinear solver object

  • X - the current solution value

  • Y - the tentative update step

  • W - the tentative new solution value

  • changed_Y - output, flag indicated Y has been changed by the post-check

  • changed_W - output, flag indicated W has been changed by the post-check

  • ctx - the optional application context
