CFD-DEM Coupling using OpenFoam and LAMMPS
 

Dear all,

for those of you that are also interested in coupling CFD with the Discrete Element Method (DEM):

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). Together with a colleague, I developed a CFD-DEM coupling via a "lammpsFoam" solver (beta stadium) based on LAMMPS. LAMMPS is a really fast solver and our "LammpsFoam" runs in parallel using MPI.

Please refer to
http://lammps.sandia.gov/movies.html#dem
where the last video http://lammps.sandia.gov/movies/gran_openfoam.avi
shows a fluidized bed calculation with LammpsFoam.

Further information can be downloaded at our homepage. At
http://fluid.jku.at/hp/index.php?opt...t_view&gid=168...
(either in zip or rar format) you can download an archive containing more sample videos in wmv format and LAMMPS input scripts.
In the "readme" file, you find a short description of LAMMPS and some words about post-processing.

LAMMPS can be downloaded at http://lammps.sandia.gov/ .

Christoph

Hello Chris,

Where can I get LammpsFoam solver? could you please forward the download link. I am very interested to see this solver. I am familiar with OpenFOAM.

Dear chris,

I need to use Lammps with openFoam to integrate particle agglomerates to a rising bubble. could you please tell me where can i find the lammpsFoam solver ?

Thank you

Dear chris

Is it possible to couple lammps with the existing interFoam solver in OpenFoam. I need to simulate a single bubble rise using interFoam and attach solid particles with potentials to the bubble interface and check for stability in attachment during bubble rise ? is this possible using Lammps and interFoam ?

thankyou
Prithvi

This can be done. There is at least a proof-of-concept on the CFDEM page: http://www.cfdem.com/cfd-dem-0

what are all the tools can i couple with fluent. like fluent-lammps.
thanks for advance.
