Line 1: <b>Discrete element methods</b> (DEM) comprise a family of related mathematical tools for determining the kinematic behavior of finite-sized particles. As defined by Cundall, ''discrete element methods'' allow 1. finite displacement, rotation and separation of elements, and <br> 2. new particle contacts are recognized algorithmically as the simulation proceeds. ~~algorithmically as the simulation proceeds.~~ Two prominent members of the DEM family are the [[distinct element method]] proposed by [[Peter A. Cundall \| Cundall]] in 1971, and the
