Original Kurzfassung:
In this work, we present the development of an open-source software
for modeling granular material by means of the Discrete Element Method.
LIGGGHTS (www.liggghts.com) stands for ?LAMMPS Improved for
General Granular and Granular Heat Transfer Simulations? and is based on
LAMMPS (?Large Atomic and Molecular Massively Parallel Simulator?), a
successful open source Molecular Dynamics code written and distributed by
Sandia National Laboratories for massively parallel computing on distributed
memory machines. We first give a brief overview of implemented models
and features. These comprise CAD geometry import, features for particle
insertion and packing, contact models, wallstress analysis, moving mesh
capability, a 6 DOF feature and non-spherical particle handling. Finally, we
would like to focus on the simulation of coupled granular-fluid systems with
the CFD-DEM approach.
