Abstract

This article reviews novel algorithms for the Discrete Element Method (DEM) with polyhedral particles to greatly improve the efficiency in particle contact detection which is the most time-consuming part of a simulation. The implemented algorithms are used in simulations designed to reproduce experimental tests on angular JSC-1A lunar regolith stimulant particles.
