Altair® EDEM™.

Discrete Element Method (DEM) Software

EDEM is high-performance software for bulk and granular material simulation. Powered by DEM, EDEM quickly and accurately simulates and analyzes the behavior of coal, mined ores, soils, fibers, grains, tablets, powders, and more.

EDEM simulation provides engineers with crucial insight into how those materials will interact with their equipment during a range of operation and process conditions. It can be used stand-alone or combined with other CAE tools.

Leading companies in the heavy equipment, off-road, mining, steelmaking, and process manufacturing industries use EDEM to understand and predict granular material behaviors, evaluate equipment performance, and optimize processes.


Instant Access to Material Models Libraries

Instant Access to Material Models Libraries

Get started with simulations quickly and easily with EDEM’s extensive range of pre-calibrated material models representing rocks, ores, soils, and powders.

High Performance Solver
