CFD DEM coupling - pimpleParticleFoam

A new solver of fluid-particle (CFD-DEM) coupling named pimpleParticleFoam, is based on OpenFOAM (CFD) , LAMMPS (with LIGGGHTS package, DEM) and cfdem schem.
The solver incooperates CFD PIMPLE (PISO+SIMPLE) scheme which supports adjustable timestep to speed up the simulation.
In the video U stands for fluid velocity contour, mass the DEM particles mass. The Coupling results have good agreement with published data.

awesome video! Thank you!

@F. L.Y. hey. it is great. Great work indeed. Will you please tell me that is there any solver available in CFDEM Coupling with LIGGGHTS with help of OpenFOAM to simulate a 2D/3D bubble in a liquid dispersed phase? The bubble follows lagrangian particle tracking (LPT) physics and the liquid obeys Eulerian physics. Please feel free to give the details. Its urgent. Waiting for your valuable reply. Thanks in advance

That is awesome. Is there anyway to get a starting material to do similar model?

How you did coupling of liggghts and openfoam

[@engineerdo6568]

Hey Abhishek, I did recently a tutorial using openFoam and Liggghts for the coupling. Glad if you check it out: th-cam.com/video/HsTRkC5EIOw/w-d-xo.html

[@supergaga]

well, it is pretty much said in the introduction of this video. You can google the relevant keywords.
good luck.

Hey please send me the blockmeshdict file

[@supergaga]

Well, since this video was made 5 years ago, I could not find the files. But it is simple to make such OpenFoam mesh: first use some 3d modeling tool like blender3D or Gmsh to create STL file. Then you can simply use OF meshing tool snappyHexMesh to create the desired mesh. You can ofc use blockmesh, but it is too trivial.
