Welcome to the ESyS-Particle Community Wiki!

What is ESyS-Particle?

ESyS-Particle is Open Source Software for particle-based numerical modelling using the Discrete Element Method (DEM); a widely adapted technique for modelling processes involving large deformations, granular flow and/or fragmentation. ESyS-Particle is best suited for execution on parallel supercomputers, clusters or multi-core PCs running a Linux-based operating system. The C++ DEM simulation engine implements spatial domain decomposition via the Message Passing Interface (MPI).

A Python wrapper API provides flexibility in the design of numerical models, including specification of modelling parameters and contact logic, as well as analysis of simulation results. ESyS-Particle has been used to simulate earthquake nucleation, silo flow, rock fragmentation and fault gouge evolution; to name but a few applications.

The ESyS-Particle Tutorial is recommended for those interested in learning how to use ESyS-Particle for DEM simulations. This wiki also hosts a range of Ancillary Documentation that may assist more advanced users. If you have questions regarding ESyS-Particle, please post them via the User Forum or consult the list of Frequently Asked Questions.

The ESyS-Particle source code is freely available for download from its Software Repository. ESyS-Particle is distributed under the terms of Apache License 2.0. Code contributions from community developers are actively encouraged.
