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().

Constructor & Destructor Documentation

◆ FastSimulationOffload()

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

Construct a model for a specific volume of space (an "envelope").

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

Member Function Documentation

◆ IsApplicable()

G4bool celeritas::FastSimulationOffload::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::FastSimulationOffload::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.
