Abstract

The grid based variation of the contact detection algorithm, with corresponding data structures, is described. This variation is tuned for numerical analysis of large, homogenously distributed assemblages of particles of fairly equal diameters. As an example, algorithm is used in the modelling of granular material silo filling and discharge.
