[lammps-users] Open Source DEM with LIGGGHTS

Dear all,

I am pleased to announce the official launch of www.liggghts.com /
www.cfdem.com along with the release of the Open Source Discrete Element
Particle Simulator LIGGGHTS, version 1.0.

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 (http://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

More features, such as improved handling for non-spherical particle, a 6
degrees of freedom solver for arbitrarily shaped bodies and wall stress
analysis, are currently under development. Also, an efficient parallel
coupling to the OpenFOAM(R) framework is under development.

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

For a complete list of features, videos, as well as downloads and tutorials,
please refer to www.liggghts.com / www.cfdem.com

If you are interested in learning more about DEM with LIGGGHTS, there will
be 2 classes (each for 3 days) held in the city of Linz, Austria. They are
scheduled for June 9-11 and September 22-24. If you are interested in
joining one of the classes, please answer to this email.

Feel free to register for free and download LIGGGHTS 1.0 from our website.
For any question that may arise, please use the provided discussions forums.

Kind regards,

Christoph Kloss
