<A HREF="../TS/TSSetPostEventIntervalStep.html#TSSetPostEventIntervalStep">TSSetPostEventIntervalStep</A> allows one to set a time-step that is used immediately following an event interval.
<P>
This function should be called from the postevent function set with <A HREF="../TS/TSSetEventHandler.html#TSSetEventHandler">TSSetEventHandler</A>().
<P>
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.
