This presentation focuses on the considerations for modelling particle solids with EDEM, introduces the philosophy and the importance of calibration. Furthermore, the participants will learn the calibration of coarse particulate solids and on the calibration approach for fine materials such as powders. Additional calibration tools, such as the GEMM Database, Calibration Kit and EDEM Cal are also introduced during this session. Goals and Objectives: Modelling approach for coarse particulate solids Modelling approach for powders and soils GEMM Database EDEM Calibration Kit EDEM Cal tool
