SNESNewtonTRDCGetPostCheck

Gets the post-check function optionally set with SNESNewtonTRDCSetPostCheck()

Synopsis

#include "petscsnes.h"   
PetscErrorCode SNESNewtonTRDCGetPostCheck(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 SNESNewtonTRDCPostCheck()

• ctx - [optional] 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
