chrono::particlefactory::ChParticleProcessor Class Reference

## Description

Class that can be used to process particles.

It uses two 'tools' that can be plugged in: 1) an object inherited from ChParticleEventTrigger, that decides IF an event must be triggered (there are ready-to-use triggers such as trigger if inside a box, if older than X, etc., or you can implement your own) 2) an object inherited from ChParticleProcessEvent, the performs an action if the event is triggered (there are ready-to-use event processors such as remove particle, etc.) Note: by default, the default trigger is ChParticleEventTriggerNever and the default particle event processor is ChParticleProcessEventDoNothing, so the default behavior is 'do nothing', so you must plug in more sophisticated ones after you create the ChParticleProcessor and before you use it.
