TSSetPostEventIntervalStep#

Set the time-step used immediately following an event interval

Synopsis#

#include "petscts.h" 
PetscErrorCode TSSetPostEventIntervalStep(TS ts, PetscReal dt)

Logically Collective

Input Parameters#

  • ts - time integration context

  • dt - post event interval step

Options Database Key#

  • -ts_event_post_eventinterval_step

    - time-step after event interval

Notes#

TSSetPostEventIntervalStep() allows one to set a time-step that is used immediately following an event interval.

This function should be called from the postevent function set with TSSetEventHandler().

The post event interval time-step should be selected based on the dynamics following the event. If the dynamics are stiff, a conservative (small) step should be used. If not, then a larger time-step can be used.
