Hi, Christoph Kloss: I am so glad to see there is another code for DEM-CFD coupling since this has been my PhD topic, I also coupled YADE with OpenFOAM:
http://fchen3.googlepages.com/discreteelementmethod I think you and I should be using the same approach originated from Prof. Tsuji? I would be very like to discuss some of the details with you, such as: 1. FVM size/particle size 2. The maximum particle number possible on a cluster 3. The parallel mechanism 4. What kind of problem/type of flow you use in your problem? 5. Is it easy to change/create new particle constitution laws for the solid phase? 6. Effect of different drag equations etc. Thank you for sharing your experience with us!!!

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 if YADE and LAMMPS could profit from each other.
