This paper aims to describe an industrial application of the Discrete Element Method (DEM). The DEM is often employed in granular and solid-fluid mixture systems. The DEM is a Lagrangian approach, where individual particles are simulated based on Newton’s second law of motion. In my group, novel models are developed to apply the DEM in industrial powder systems, i.e., coarse grain model of the DEM for efficient calculation of large-scale powder systems and combination of signed distance functions and immersed boundary method for efficient creation of arbitrary shaped wall boundary. These models are shown to be crucial for a numerical simulation of an industrial powder system.
