Hi, Discrete element method is the numerical method of modelling a large number of particles, their stresses and displacements. It can be used as for granular material simulating as well as solid materials (rocks, concrete etc.).
I think wikipedia explains better, than me: http://en.wikipedia.org/wiki/Discrete_element_method "A discrete element method (DEM), also called a distinct element method is any of family of numerical methods for computing the motion of a large number of particles of micrometre-scale size and above. Though DEM is very closely related to molecular dynamics, the method is generally distinguished by its inclusion of rotational degrees-of-freedom as well as stateful contact and often complicated geometries (including polyhedra). With advances in computing power and numerical algorithms for nearest neighbor sorting, it has become possible to numerically simulate millions of particles on a single processor. Today DEM is becoming widely accepted as an effective method of addressing engineering problems in granular and discontinuous materials, especially in granular flows, powder mechanics, and rock mechanics." The YADE is mostly developed and used in universities and scientific laboratories in France, Great Britain, Czech Republic, Russia... Developers are PHD-students, Post-docs and scientists.
