Boundary conditions and machine interactions: overlooked aspects of a simulation

Abstract

The popularity of the Discrete Element Method (DEM) has grown significantly in the past decade, driven by the significant improvements that have been made in computing hardware, particularly with the recent developments in the use of GPUs for scientific computation. Simulations of millions of particles are now commonplace as people seek to extract more detailed information from them. However, in many cases, as we strive to make our simulations as simple as possible, we often neglect the importance of complex machine interactions, simplifying their movements or shapes. For engineers or scientists trying to understand the forces and stresses acting in their systems, these simplifications may lead to critical information being lost or overlooked. Conversely, including a boundary where none exists in the real system may also lead to incorrect interpretation of the results.

Research Scientist in Granular Mechanics

My research interests include particulate mechanics, the Discrete Element Method (DEM) and other numerical simulation tools. I’m also interested in all things data and how to extract meaningful information from it.
