TSSetTimeStep

Allows one to reset the timestep at any time.

Synopsis

#include "petscts.h"  
PetscErrorCode TSSetTimeStep(TS ts, PetscReal time_step)

Logically Collective

Input Parameters

• ts - the TS context obtained from TSCreate()

• time_step - the size of the timestep

Options Database Key

• -ts_time_step

  - provide the initial time step

Notes

This is only a suggestion, the actual initial time step used may differ

If this is called after TSSetUp(), it will not change the initial time step value printed by TSView()
