The corresponding discrete element model, assumed to have been scaled, is a geometrically exact representation of the physical problem, i.e. both models have the same particle number and particle packing configuration, and the particle sizes and the domains in the two models are different only by a constant (spatial) scale factor \(h\). The particle properties and interaction laws can be inserted into a discrete element model (DEM), which then follows the evolution of Newtons equations of motion for the dissipative, frictional, cohesive many-particle system under observation [1{3].
