MechSys is a programming library for the implementation of simulation tools in mechanics. Its source code is mainly written in C++ with parts in Python and Go (under development).
Potential applications include, for instance, solid mechanics using the finite element method, mechanics of granular materials using the discrete element method, and computational fluid dynamics using the lattice Boltzmann method.
See: References below for papers produced with MechSys.
See: Mailing list for a forum for discussions and Q&A: MechSys' mailing list.
The Discrete Element Method in MechSys can handle particles of many different shapes.
This library includes (among others):
