LBDEMcoupling

LBDEMcoupling: open-source power for fluid-particle systems. We present LBDEMcoupling, a coupling between the LBM code Palabos and the DEM code LIGGGHTS to perform resolved simulations of fluid-particle systems. We show correctness of the model by comparing simulations of a settling sphere to experimental data. Further, the computational efficiency of the implementation is demonstrated. Finally, we show that LBDEMcoupling is capable of correctly depicting the onset of sediment motion for a bed of particles under shear flow.
