Hi Dear all,
I am trying a CFD-DEM simulation of one particle falling down with only gravity in a vessel. I can not run the simulation even with one time step due to the convergence problem.
mfix.dat is attached to see more. Any help? Thank you.

I got the answer: to use a cyclic BC in the y-direction.
