Granular media are systems of macroscopic particles that interact mainly through contact forces. Granular media abound in nature and industry, but are not well understood. Recent laboratory experiments on granular media in oscillated containers have revealed a variety f collective phenomena--heaping, segregation, compaction, convection, spatial patterns, and clustering. The speakers in this minisymposium will describe the phenomena and molecular dynamics simulations developed to understand them. The simulations assume that the particles obey Newton's laws and that energy is dissipated in collisions. While simulations and pde models provide many open questions.
