PetscErrorCode TSSetPostEventIntervalStep(TS ts,PetscReal dt)
Logically Collective

dt - post event interval step

-ts_event_post_eventinterval_step <dt> 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.
