Lees-Edwards Boundary Condition in CFDEM

Submitted by mofazli on Fri, 07/31/2020 - 02:59

Hi all,
I wanna implement the Lees-Edwards boundary condition (a mixture of periodic boundary condition and simple shear flow) on cfdemSolverIB. However, I didn't find anything on the papers regarding how it can be imposed on CFD and DEM separately. As we know, the position and velocity of fluid and particles should be updated every time step in Openfoam and DEM. The DEM (liggghts) part seems more tricky to me. Is there anyone who investigated this topic?
Thank you for your help.
