Discrete element method simulation of non-sphere particles using super-ellipsoids

摘要

Since granular systems is common in many industrial processes and the movement of the particles is extremely complicated, it's meaningful to study the physics of the granular materials by discrete element method (DEM), which has been recognized as an effective and efficient way. A series of models have been proposed to simulate the non-sphere particles, such as glued spheres, polyhedral, super-ellipsoids, and some kinds of real shape models like ellipsoid. Among them, super-ellipsoids model has advantages on many aspects.
