Constructor Summary

QuantumVelocityUpdateStrategy()
Create a new instance of QuantumPositionUpdateStrategy.

QuantumVelocityUpdateStrategy(StandardVelocityUpdate copy)
Create an copy of the provided instance.

Method Summary

void	updateVelocity(Particle particle) Update particle velocity; do it in a standard way if the particle is neutral, and do not update it if the particle is quantum (charged), since quantum particles do not use the velocity to update their positions.
