ESyS-Particle is Open Source software for particle-based numerical modelling. The software implements the Discrete Element Method (DEM), a widely used technique for modelling processes involving large deformations, granular flow and/or fragmentation. ESyS-Particle is designed for execution on parallel supercomputers, clusters or multi-core PCs running a Linux-based operating system (or Windows 10 with WSL installed). The C++ simulation engine implements spatial domain decomposition via the Message Passing Interface (MPI). A Python wrapper API provides flexibility in the design of numerical models, specification of modelling parameters and contact logic, and analysis of simulation data. ESyS-Particle has been used to simulate earthquake nucleation, comminution in shear cells, silo flow, rock fragmentation, and fault gouge evolution, to name but a few applications.

The ESyS-Particle source code is distributed under the Apache License v2.0 and maintained via the ESyS-Particle Launchpad Repository.

New users are encouraged to read the ESyS-Particle Tutorial. User support is provided via the ESyS-Particle User Forum.

Installation instructions and other useful information is provided via the ESyS-Particle FAQ.

The ESyS-Particle Python API Documentation provides a reference guide for all available features of the software.

This website provides additional notes, documentation and examples on ESyS-Particle and its usage.
