The mechanical behavior of granular materials can be usefully described in terms of continuum fields such as stress, strain, porosity, and mass density. These fields and their derivatives are often of interest when modelling granular systems with Altair EDEM. An example is the calculation of the kinetic stress field in a powder mixer, which is used to analyze the convective flow patterns in the system. The EDEMpy library of python functions enables the calculation of such continuum fields from discrete particle data in EDEM and this talk gives an overview of continuum analysis with EDEMpy using a powder mixing process as a case study.
Presented as part of the virtual ATCx Discrete Element Method in November 2020.
