Calibrating the microparameters of DEM models using the ant colony optimization algorithm and the optimal hyperparameters

Abstract Particle flow code (PFC) is a typical discrete element method (DEM) that is commonly used to simulate the mechanical behaviour of granular materials. However, the micro-parameters should be calibrated when the PFC is used for numerical simulation, and the commonly used trial-and-error techn...
