Discrete Element Method (DEM or EDEM)

Discrete Element Method (DEM), also known as EDEM (Engineering Discrete Element Method), is a numerical simulation technique used to model and analyze the behavior of granular materials, such as particles, powders, and grains. The method simulates the motion and interaction of individual particles and their contacts with each other and with other surfaces or boundaries.

DEM/EDEM works by dividing the granular material into discrete elements and representing each element as a rigid body with mass, position, and orientation. The method then uses mathematical equations to simulate the motion and interaction of these elements, taking into account the forces and torques that act on them, including gravitational, inertial, and contact forces.

DEM/EDEM is used in a wide range of industries, including mining, pharmaceuticals, food processing, and construction, to study the behavior of granular materials under various conditions, such as in transportation, mixing, and packing processes. It can be used to optimize the design of equipment and processes, reduce waste, and improve product quality and performance.
