Sets the general-purpose function called once at the end of each step evaluation.


#include "petscts.h"  
PetscErrorCode  TSSetPostEvaluate(TS ts, PetscErrorCode (*func)(TS))
Logically Collective on TS

Input Parameters

ts - The TS context obtained from TSCreate()
func - The function

Calling sequence of func

PetscErrorCode func(TS ts); -


Semantically, TSSetPostEvaluate() differs from TSSetPostStep() since the function it sets is called before event-handling thus guaranteeing the same solution (computed by the time-stepper) will be passed to it. On the other hand, TSPostStep() may be passed a different solution, possibly changed by the event handler. TSPostEvaluate() is called after the next step solution is evaluated allowing to modify it, if need be. The solution can be obtained with TSGetSolution(), the time step with TSGetTimeStep(), and the time at the start of the step is available via TSGetTime()
