Open Source DEM with LAMMPS

Dear esys particle users and developers,

I would like to bring the DEM capabilities of LAMMPS to your attention. LAMMPS is an open source molecular dynamics code that also provides possibilities for DEM simulations (thanks to algorithmic and physical analogies). LAMMPS is on the open source "market" since the mid90s.
It is thus quite mature, very fast and provides excellent documentation.

Please refer to the homepage http://lammps.sandia.gov/ for download and documentation.

For some simulation examples, please refer to http://lammps.sandia.gov/movies.html#dem

The final movie ( http://lammps.sandia.gov/movies/gran_openfoam.avi ) shows a new capability that my colleague Christoph Goniva and I have developed to perform CFD-DEM simulations by coupling LAMMPS to the OpenFoam computational fluid dynamics (CFD) package. This allows us to run CFD-DEM simulations on clusters using MPI parallelism.

Some more videos and sample input scripts can be found at
http://fluid.jku.at/hp/index.php?option=com_docman&task=cat_view&gid=168

LAMMPS is written in C++ and very easy to modify. If you are interested in LAMMPS, you are welcome to contact me! I would be happy to start off a discussion. Maybe esys particle and LAMMPS can profit from each other.

Kind regards from Austria,

Christoph Kloss
