TSPseudoSetTimeStep
Sets the user-defined routine to be called at each pseudo-timestep to update the timestep.
Synopsis
int TSPseudoSetTimeStep(TS ts,int (*dt)(TS,double*,void*),void* ctx)
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 PETSC_NULL)
|
Calling sequence of func
func (TS ts,double *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.
