Here is a space-time picture of the evolution of a system of 500 particles in
one dimension which undergo inelastic collisions, with restitution
coefficient r=0.9 up to time=600. As a time-saving feature, if the relative
velocity between 2 collision partners is less than 0.01, a purely elastic
collision is implemented. For more details see Shock-Like Dynamics of Inelastic Gases, |
