Welcome to Yade - Open Source Discrete Element Method

Yade is an extensible open-source framework for discrete numerical models, focused on Discrete Element Method. The computation parts are written in c++ using flexible object model, allowing independent implementation of new alogrithms and interfaces. Python is used for rapid and concise scene construction, simulation control, postprocessing and debugging.

Yade is located at yade-dem.org, which contains this documentation and wiki. Development is kindly hosted on launchpad and GitLab ; they are used for source code, bug tracking and source downloads and more. Building, regression tests and packages distribution are hosted on servers of the Grenoble Geomechanics group at Laboratoire 3SR, UMS Gricad and Gdańsk University of Technology.

Since May 2019 python 3 replaces python 2 in Yade. See installation prerequisites to install new python 3 dependencies, Python 2 backward compatibility installation to force the python version you want to use, and convert-python-2-scripts-to-python-3 section for informations about converting your scripts.

Since March 2012 Yade is using GIT as VCS. The main branches are currently on GitLab (migrated from GitHub in January 2019).
