Detailed Description

Standard INCL4 particle propagation and avatar prediction

This class implements the standard INCL4 avatar prediction and particle propagation logic. The main idea is to predict all collisions between particles and their reflections from the potential wall. After this we select the avatar with the smallest time, propagate all particles to their positions at that time and return the avatar to the INCL kernel

See Also

G4INCL::Kernel.

The particle trajectories in this propagation model are straight lines and all particles are assumed to move with constant velocity.

void G4INCL::StandardPropagationModel::generateCollisions	(	const ParticleList &	particles,

Generate and register collisions among particles in a list, except between those in another list.

This method generates all possible collisions among the particles. Each collision is generated only once. The collision is NOT generated if BOTH collision partners belong to the except list.

You should pass an empty list as the except parameter if you want to generate all possible collisions among particles.

Parameters

particles	list of particles
except	list of excluded particles

void G4INCL::StandardPropagationModel::generateUpdatedCollisions	(	const ParticleList &	updatedParticles,

Generate and register collisions between a list of updated particles and all the other particles.

This method does not generate collisions among the particles in updatedParticles; in other words, it generates a collision between one of the updatedParticles and one of the particles ONLY IF the latter does not belong to updatedParticles.

If you intend to generate all possible collisions among particles in a list, use generateCollisions().

Parameters

updatedParticles	list of updated particles
particles	list of particles
