esys-particle - 2.3.5+dfsg1-2.1 main

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. 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
utilised to simulate earthquake nucleation, comminution in shear cells, silo
flow, rock fragmentation, and fault gouge evolution, to name but a few
applications.
