chrono::particlefactory::ChParticleEventFlowInRectangle Class Reference

Description

Trigger an event each time a particle flows into a rectangle.

Rectangle is defined with a coordinate system, in the center, and two X Y sizes. This is triggered only if the particle is flowing from positive Z to negative Z. Note! there is a 'margin' parameter that must be greater than zero: only particles that in the neighborhood of the rectangle (less distant than the margin) are considered, to save computational time. Too small margin might miss some fast-travelin particles, so margin should be at least 'max particle speed' * dt.

SetupPostProcess()

virtual void chrono::particlefactory::ChParticleEventFlowInRectangle::SetupPostProcess ( ChSystem & msystem )

inlinevirtual

Children classes might optionally implement this.

The ChParticleProcessor will call this once, after each ProcessParticles()

Reimplemented from chrono::particlefactory::ChParticleEventTrigger.

TriggerEvent()

virtual bool chrono::particlefactory::ChParticleEventFlowInRectangle::TriggerEvent ( std::shared_ptr< ChBody > mbody, ChSystem & msystem )

inlinevirtual

This function triggers the a particle event according to the fact the the particle is crossing a rectangle.

Implements chrono::particlefactory::ChParticleEventTrigger.
