Hello,
I would like to make some DEM simulations in constraint geometries,
which later should be coupled to a OF fluid solver. Therefore i have some
questions on the capabilities of the OpenFOAM MD solver.

1. I read that the OF solver is used for microfluiddynamics where the particle
size (molecule) is much smaller than the given mesh. My question is there
is a problem if the particles are much larger than the fluid mesh
(in my case the particles should be suspended in the fluid flow)
2. How is the interaction with the boundary modeled and what would happen
if the particles are much larger than the given mesh spacing.


thanks a lot
