Detailed Description

Offload tracks to Celeritas via G4VFastSimulationModel interface.

This class must be constructed locally on each worker thread/task, typically within the application's concrete implementation of G4VUserDetectorConstruction::ConstructSDandField().

Note that the argument G4Envelope is a type alias to G4Region.

Todo:: Maybe need a helper to create a single fast sim model for multiple regions?

Constructor & Destructor Documentation

◆ FastSimulationModel()

celeritas::FastSimulationModel::FastSimulationModel	(	G4String const &	name,
		G4Envelope *	region,
		SharedParams const *	params,
		LocalTransporter *	local
	)

Construct and build a fast sim manager for the given region.

The envelope cannot be nullptr as this will cause a segmentation fault in the G4VFastSimulation base class constructor.

Member Function Documentation

◆ Flush()

void celeritas::FastSimulationModel::Flush ( )

Complete processing of any buffered tracks.

Note that this is called in G4EventManager::DoProcessing(G4Event*) by G4GlobalFastSimulationManager after the main tracking loop has completed. That is done to allow for models that may add "onload" particles back to Geant4.

◆ IsApplicable()

G4bool celeritas::FastSimulationModel::IsApplicable ( G4ParticleDefinition const & particle )

final

Return true if this model can be applied to the input G4ParticleDefinition .

Purely checks if the particle is one that Celeritas has been setup to handle.

◆ ModelTrigger()

G4bool celeritas::FastSimulationModel::ModelTrigger ( G4FastTrack const & track )

final

Return true if model can be applied given dynamic particle state in G4FastTrack .

Always returns true because we only make the decision to offload to Celeritas based on geometric region and particle type.
