Discrete Element Method

Discrete Element Method (DEM) is a method for computing the motion of a large number of particles like molecules or grains of sand. DEM describes the contacts and movement of those discrete particles and DEM manages information about each individual particle (mass, temperature, velocity and so on) and the forces acting on it. It can also take into account the particle’s shape, rather than assuming that all particles are spherical. DEM can be coupled with Computational Fluid Dynamics (CFD) so fluid forces acting on the discrete particles can be included as well. Discrete element methods are processor intensive and this limits either the length of a simulation or the number of particles but advances in the software and hardware are beginning to take advantage of parallel processing capabilities to scale up the number of particles or length of the simulation.
