Non-resolved non-spherical particles

LIGGGHTS® features high-performance, open source, customizable DEM simulations.
It allows non-resolved handling of non-spherical particles by rolling-friction models

This means that the interlocking effect of non-sperical particles if depicted by torques which oppose the relative rotational motion. LIGGGHTS® incorporates simple rolling friction models as well as elasto-plastic rolling friction models

Example - angle of repose
