TSSetPostStage#

Sets the general-purpose function, provided with TSSetPostStep(), called once at the end of each stage.

Synopsis#

#include "petscts.h"  
PetscErrorCode TSSetPostStage(TS ts, PetscErrorCode (*func)(TS, PetscReal, PetscInt, Vec *))

Logically Collective

Input Parameters#

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

Calling sequence of `func`#

  PetscErrorCode func(TS ts, PetscReal stagetime, PetscInt stageindex, Vec* Y)

Note#

There may be several stages per time step. If the solve for a given stage fails, the step may be rejected and retried. The time step number being computed can be queried using TSGetStepNumber() and the total size of the step being attempted can be obtained using TSGetTimeStep(). The time at the start of the step is available via TSGetTime().
