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.

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
