PyGran is a simulation and analysis toolkit designed for particle systems with emphasis on discrete element method (DEM) simulation. PyGran enables DEM programmers to develop computational tools and perform interactive analysis of granular systems in Python. The toolkit provides an interface for running DEM simulations in parallel using the open-source LIGGGHTS-PUBLIC software, routines for performing structural and temporal analysis, and an intuitive way for building and manipulating granular systems. The object-oriented design of PyGran enables post-processing of coupled CFD–DEM simulation, and constructing coarse-grained representations of DEM systems. PyGran is released under the GNU General Public License (GPL v2.0), and its source code is available from github.
