spanning from geophysical phenomena, such as avalanches and sand dune formation,
to industrial and defense applications, through powder technology, additive
manufacturing, and the mechanics of soil and construction materials. While the study of
monodisperse spheres has progressed significantly over the past two decades, here we
explore more recent developments that allow us to extend computer simulation studies
to systems that more closely relate to real-world and experimental systems. These
include the capability to study systems with a high degree of particle size dispersity,
non-spherical, complex, and frictional particle shapes, that can pack or flow in different
geometries. We illustrate these newer capabilities with the study of the inclined plane
flow of rod-like structures, and how the flow behavior depends on the size of the flowing
pile and the frictional roughness between the rods.
