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.
