About CFDEM®project

Open Source and Beyond: Particle Simulation for Science and Industry


Particles and flow processes are everywhere  – in industry, the environment, and everyday life. Sugar, sand, ores, tablets, chemicals, biomass, detergents, plastics, crops, and fruits all need to be harvested, produced, processed, transported, and stored. Computational simulation of these particle and fluid flow processes is key to understanding, designing, and improving them.

The CFDEM®project is dedicated to advancing these capabilities through both open-source and professional tools:

- LIGGGHTS® – the open-source Discrete Element Method (DEM) software
CFDEM®coupling – the open-source CFD-DEM coupling software
- Aspherix® - the commercial DEM software, developed as the successor to LIGGGHTS®

While LIGGGHTS® and CFDEM®coupling continue to thrive as open-source community projects, Aspherix® represents the next generation: a distinct, professional-grade DEM software. It offers advanced features, enhanced performance, and expert support, enabling research and industry users to go further than ever before. Find out more about Aspherix® here.

All contributions to LIGGGHTS® and CFDEM®coupling are documented in the release notes. In addition, snapshots of applications and research from the global CFDEM®project community.
