TSPseudoSetTimeStep

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

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

Logically Collective on TS

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

 func (TS ts,PetscReal *newdt,void *ctx);

	newdt	- the newly computed timestep
	ctx	- [optional] timestep context

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