Dear CFX-Colleagues,

I require the transient tracks of mulitple spheres close to a small opening in a wall, and the mutual interactions. This is problem where Lagrangian particle tracking nor Eulerian multiphase is suitable anymore.

Therefore I have to consider other approaches that take the particle volume and their interactions into account. Does anyone have any experience in this using add-ons like EDEM in combination with CFX, or any other software package, and is willing to share it here?

Alternatives to CFX could be Fluent which has MDM. However, I consider that as unsuitable as it requires a too fine grid. I could use their oversetmeshing with 6DOF, but I expect that to be too time consuming for multiple particles.

Outside ANSYS, there is DEM in Star-CCM+, or RockyDEM. Does anyone have experience with that? Or open-source DEM codes such as YADE and LIGGGHTS. Or something completely different?

(I'll ask this quesiton in the other forums as well, but prefer to start here.....)

Regs, Gert-Jan
