Aspherix® is available under commercial license and combines DCS’s learnings from the development of LIGGGHTS® and a large set of new, cutting edge features. For more information, please visit https://www.aspherix-dem.com/.
Cronology of the development:
- LAMMPS: core development by Sandia Corporation since 2003
- LIGGGHTS® core development by DCS Computing GmbH and JKU Linz since 2009
- Aspherix®: core development by DCS Computing GmbH since 2019
LIGGGHTS®-PUBLIC is an Open Source Discrete Element Method Particle Simulation Software, distributed by DCS Computing GmbH, Linz, Austria. LIGGGHTS® is a registered trade marks of DCS Computing GmbH, the producer of the LIGGGHTS® software; see http://www.cfdem.com/terms-trademark-policy for details.
LIGGGHTS®-PUBLIC is open-source, distributed under the terms of the GNU Public License, version 2 or later. LIGGGHTS®-PUBLIC is part of CFDEM(R)project: www.liggghts.com | www.cfdem.com Core developer and main author: Christoph Kloss, christoph.kloss@dcs-computing.com
All LIGGGHTS® versions are based on a specific version of LIGGGHTS®, as printed in the file src/version.h. LIGGGHTS® versions are identidied by a version number (e.g. ‘3.0’), a branch name (which is ‘LIGGGHTS®-PUBLIC’ for your release of LIGGGHTS), compilation info (date / time stamp and user name), and a LAMMPS version number (which is the LAMMPS version that the LIGGGHTS®-PUBLIC release is based on). The LAMMPS “version” is the date when it was released, such as 1 May 2010.
If you browse the HTML doc pages on the LIGGGHTS®-PUBLIC website (https://www.cfdem.com/media/DEM/docu/Manual.html), they always describe the most current version of LIGGGHTS®-PUBLIC. If you browse the HTML doc pages included in your tarball, they describe the version you have.
Some parts of LIGGGHTS® are based on LAMMPS. LAMMPS stands for Large-scale Atomic/Molecular Massively Parallel Simulator. LAMMPS is Copyright (2003) Sandia Corporation. Under the terms of Contract DE-AC04-94AL85000 with Sandia Corporation, the U.S. Government retains certain rights in this software. This software is distributed under the GNU General Public License.
LAMMPS is a classical molecular dynamics simulation code designed to run efficiently on parallel computers. It was developed at Sandia National Laboratories, a US Department of Energy facility, with funding from the DOE. It is an open-source code, distributed freely under the terms of the GNU Public License (GPL).
The primary author of LAMMPS is Steve Plimpton, who can be emailed at sjplimp@sandia.gov. The LAMMPS WWW Site at lammps.sandia.gov has more information about the code and its uses.
