Abstract
The purpose of this article is twofold: to present the physics of granular media, to emphasise modern principles and research topics, and to discuss the models most applicable to the simulation of these phenomena by machine. There is a thorough discussion of soft-particle molecular dynamics, event-driven molecular dynamics, Moreau and Jean's touch dynamics, and the bottom-to-top-restructuring model.
