TSPseudoSetTimeStep

Sets the user-defined routine to be called at each pseudo-timestep to update the timestep.

Synopsis

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

Input Parameters

ts - timestep context
dt - function to compute timestep
ctx - [optional] user-defined context for private data required by the function (may be NULL)

Calling sequence of func

func (TS ts,PetscReal *newdt,void *ctx); -
newdt -the newly computed timestep
ctx -[optional] timestep context

Notes

The routine set here will be called by TSPseudoComputeTimeStep() during the timestepping process. If not set then TSPseudoTimeStepDefault() is automatically used

Keywords

timestep, pseudo, set
