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 ts, Vec update, void *ctx, PetscReal *newdt, PetscBool *flag), void *ctx)
Logically Collective
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#
- ts - the time-step context 
- update - latest solution vector 
- ctx - [optional] user-defined timestep context 
- newdt - the timestep to use for the next step 
- flag - flag indicating whether the last time step was acceptable 
Note#
The routine set here will be called by TSPseudoVerifyTimeStep()
during the timestepping process.
