Multiscale Modelling of Particulate Solids – Linking the Particle and Continuum Scales

Stefan Pantaleev, Lead Solutions Specialist at Altair presents at the 2024 ATCx DEM.

Understanding the complex behaviour of particulate solids at the particle scale is important in a wide range of industries where particle properties determine equipment performance and product quality. Particle scale modelling methods such the Discrete Element Method (DEM) provide unprecedented insight into particulate material micro-mechanics but are often too computationally expensive to simulate large quantities of material. Continuum approaches based on the Finite Element Method (FEM) have the required computational efficiency but are incapable of resolving the micro-mechanics. A multi-scale modelling methodology that combines the two methods is therefore required to enable practical solutions. This talk discusses possible multi-scale modelling strategies using Altair EDEM in combination with other simulation and machine learning tools in the Altair portfolio.
