What is DEM – An Introduction to the Discrete Element Method

WATCH RECORDING

This webinar was presented live on Tuesday, 18th September, 2018.

The Discrete Element Method (DEM) is a particle-scale numerical method for modeling the bulk behavior of granular materials and many geomaterials such as coal, ores, soil, rocks, aggregates, pellets, tablets and powders.

Webinar about 'What is DEM'

This method has been applied to simulate and analyze flow behavior in a wide range of disciplines including pharmaceutical and process engineering, mechanical engineering, materials science, agricultural engineering and more.

In this webinar, we will introduce the Discrete Element Method (DEM) and the theoretical background behind it.
