Event-driven molecular dynamics is often used to simulate hard or piecewise continuous models (rather than the more familiar time-driven molecular dynamics used for soft models). An example of an event is a collision. One of the first examples of the use of such an algorithm was in the study of hard disks in 1959 [1]. The application of event-driven molecular dynamics to non-circular/spherical particles is substantially more challenging [2]
