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.
