What is the best solver used for modeling motion of the granular medium?

Hi!
I've got a question:
What is the best solver used for modeling motion of the granular medium?
I mean bulk solids, such as sand or gravel.
Is it possible with OpenFoam?

Best regards
Shakir.

lagrangian is the key word you are dealing with

Another keyword: DEM (Discrete (Distinct) Element Method (Model)). There are some solvers meant specifically for this, e.g., YADE; and then there is LIGGGTHS, based on a molecular dynamics solver LAMMPS, coupled to OF to produce CFD-DEM.

Or you can kludge your own app for that, like I did some time ago...

Hi r08n!
Thank you for replying me!
I consider the granular medium as a non-Newtonian fluid. But I have no experience in writing their applications for OpenFOAM.
I would be very grateful if you could send me your application and test case for studying!

With best wishes
Shakir

Let me show you my way of calculating bulk solids behavier. You can find the theoretical discription (in German) and a small software programm under these links

Hi i model debris flows and adapted the 4-way coupling of DPMFoam to my debris flow adapted version of interMixingFoam debrisInterMixing in debrisInterMixingLP- but to couple to large colliding particles that can do resolved CFD-DEM by clamping several particles together, the current best way is the coupling of YADE-OpenFOAM, https://yade-dem.org/doc/FoamCoupling.html
the interMixingFoam-DPMFoam based debrisInterMixingLP coupled well with YADE, based on YADE-OpenFOAM, only the limitations to stokes drag have to be extended to account for all particle forces and cell-dependent viscosity and density.
