Yade

Yade is an extensible open-source framework for discrete numerical models, focused on Discrete Element Method. The project started as an offspring from SDEC at Grenoble University, now is being developed at multiple research institutes and has active and helpful user community.

The computation parts are written in c++ using flexible object model, allowing independent implementation of new alogrithms, interfaces with other software packages (e.g. flow simulation), data import/export routines. Python can be used to create and manipulate the simulation or for postprocessing.

This wiki contains general discussions and overview of Yade and modules. Users are encouraged to introduce themselves present their work here.

Detailed reference documentation and theoretical background are here.

Source code and development website (bugs, blueprints, mailing lists) are hosted by launchpad.
