Hi group,

just want to draw your attention to the DEM package LIGGGHTS.

LIGGGHTS stands for LAMMPS Improved for General Granular and Granular Heat Transfer Simulations. As this name implies, it is based on the Open Source MD code LAMMPS. LAMMPS is a widely used, well documented, high performance simulator written by Steve Plimpton, Paul Crozier, Aidan Thompson and others at Sandia National Laboratories, Albuquerque, US (lammps.sandia.gov). LAMMPS also offers a "GRANULAR" package for DEM simulations.

LIGGGHTS now brings these DEM features to a new level. The following features have been implemented on top of the LAMMPS "GRANULAR" features:
+ A re-write of the contact formulations, including the possibility to define macroscopic particle cohesion
+ Import and handling of triangular meshes from CAD A moving mesh feature
+ Improved particle insertion
+ A model for heat generation and conduction between particles in contact
+ wall stress analysis

More features, such as improved handling for non-spherical particle, a 6 degrees of freedom solver for arbitrarily shaped bodies and are currently under development.

Also, an efficient parallel coupling to the an open source CFD framework is under development.

LIGGGHTS will stay "backward compatible" to LAMMPS, meaning in can use all powerful LAMMPS features.
