Discrete element models of particle flows
Mathematical Modelling and Analysis, 2001 Particle flows occur in a very wide range of industrial applications. In a Discrete element model (DEM) the motions of the individual particles in the system are tracked.

A variational integrator for the Discrete Element Method [PDF]
Journal of Computational Physics, 2022 A novel implicit integration scheme for the Discrete Element Method (DEM) based on the variational integrator approach is presented. The numerical solver provides a fully dynamical description that, notably, reduces to an energy minimisation scheme in the quasi-static limit.

Multiscale Discrete Element Modeling
Symmetry, 2021 A multiscale approach to discrete element modeling is presented. A distinctive feature of the method is that each macroscopic discrete element has an associated atomic sample representing the material’s atomic structure. The dynamics of the elements on macro and micro levels are described by systems of ordinary differential equations, which are solved ...
