Discrete Element Method

The Discrete Element Method (DEM) is a computational technique used to simulate and analyze the behavior of groups of individual particles, like grains of sand or powders. By modeling each particle's position, movement, and interactions—such as contact forces and friction—DEM helps scientists and engineers predict how these materials behave under different conditions. It's widely used in fields like geology, pharmaceuticals, and materials science to understand phenomena like flow, packing, and stress distribution in granular materials, providing detailed insights that are difficult to observe through experiments alone.
