Realistic yet efficient representation of particle shape is a major challenge for the Discrete Element Method. This paper uses angle-of-repose and direct-shear test simulations to describe the influence of several shape representation methods, and th

Multi-spheres and Superquadrics are popular approaches for addressing particle shape effect in the Discrete Element Method (DEM). This study focuses on the mechanical characteristics of cubical particles, modeled by the two methods (using EDEM and LI

In Discrete Element Method (DEM) simulations, particle–particle contact laws determine the macroscopic simulation results. Particle-based contact laws, in turn, commonly rely on semi-empirical parameters which are difficult to obtain by direct micr

Discrete Element Method (DEM) and DEM coupled to Computational Fluid Dynamics (CFD-DEM) are powerful techniques for optimization and design of particle processes. Macroscopic granular particles or flow involving fluids and granular particles are ever

In this paper we follow the work of [7] to evaluate the scalability of contact law for a linear spring dashpot (LSD) model. Models are evaluated using a shear test box with Lees-Edwards boundary conditions. Afterwards we extend our analysis for a Her
