Altair EDEM is the market-leader in Discrete Element Method (DEM) technology for bulk and granular material simulation.

First introduced to the market in 2006 by DEM Solutions, Ltd., EDEM software is used for virtual testing of equipment that handles or processes bulk materials in the manufacturing of mining, construction, off-highway and agricultural machinery, as well as in the mining and process industries.

Blue-chip companies around the world use EDEM to optimize equipment design, increase productivity, reduce costs of operations, shorten product development cycles and drive product innovation. In addition, EDEM is used for research at over 300 academic institutions worldwide.

In November 2019, DEM Solutions Ltd. was acquired by Altair, a global technology company providing solutions in product development, high-performance computing and data analytics. EDEM is now part of the Altair solution portfolio and remains available globally through Altair and a robust network of channel partners.
