- ItemOpen AccessAn assessment of software packages as applied to particles in a rotating mill(2001) Sonn, Leigh M; Nurick, Gerald NThis thesis evaluates three different software packages to test their potential use i ncomminution. The packages are ELFEN, ABAQUS and Particle Flow Code (PFC²D). The numerical codes differe in the method of inputting data as well as the theoretical models used. ELFEN and ABAQUS are finite element (FEM) packages wheras PFC²D uses the discrete element method (DEM). The packages also differ in the integration and contact schemes, as well as the method used to calculate the critical time step in the analysis.
