TSPseudoSetVerifyTimeStep

Sets a user-defined routine to verify the quality of the last timestep.

Synopsis

#include "petscts.h"   
PetscErrorCode  TSPseudoSetVerifyTimeStep(TS ts,PetscErrorCode (*dt)(TS,Vec,void*,PetscReal*,PetscBool*),void *ctx)
Logically Collective on TS

Input Parameters

ts - timestep context
dt - user-defined function to verify timestep
ctx - [optional] user-defined context for private data for the timestep verification routine (may be NULL)

Calling sequence of func

func (TS ts,Vec update,void *ctx,PetscReal *newdt,PetscBool *flag); -
update -latest solution vector
ctx -[optional] timestep context
newdt -the timestep to use for the next step
flag -flag indicating whether the last time step was acceptable

Notes

The routine set here will be called by TSPseudoVerifyTimeStep() during the timestepping process.

Keywords

timestep, pseudo, set, verify
