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 ts, PetscReal *newdt, void *ctx), void *ctx)
Logically Collective
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 dt#
- ts - the - TScontext
- newdt - the newly computed timestep 
- ctx - [optional] user-defined context 
Notes#
The routine set here will be called by TSPseudoComputeTimeStep()
during the timestepping process.
If not set then TSPseudoTimeStepDefault() is automatically used
