Numerics of Discrete Element Simulations in Milli-g Environments: Challenges and Solutions

Abstract

This work gives an overview of numerical issues arising when performing DEM soil simulations in milli-g environments. The cause for those issues as well as their effect on simulation results and numerical stability are discussed. Lastly, strategies and solutions to avoid numerical issues with floating-point arithmetics in milli-g environments are proposed, implemented and their effectiveness is reviewed.
