Calibration is a crucial step in DEM to ensure that the virtual materials accurately represent real particles. Further, every bulk material is unique and unlike CFD or FEA simulations, standard values for materials will not always provide an accurate representation of the real particles. The Rocky Calibration suite provides engineers with 8 Rocky calibration projects to help automate the often lengthy calibration process by replicating standard material calibration tests.<\/p>

In the latest Rocky 2022 R1 release, a new application in the form of a Pre-Post Script further streamlines the calibration process by automatically adjusting the initial parameters needed to calibrate the materials efficiently. Rocky\u2019s new Material Wizard is a quick and straightforward tool that can jumpstart calibration work given experimentally measurable qualities like bulk density, angle of repose, and cohesion type. The engineer can input experimentally obtained values or choose from a broader range.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

\n\t\t\t\tCapturing the complex behavior of this \u201csticky\u201d material in a simulation environment is a challenge. To understand and predict the flow of iron-ore fines, Onyx Projects in collaboration with ESSS & LEAP developed simulated shear cell experiments to calibrate the flowability of different Iron-ore fines materials at different moisture levels to capture the full range of real flow behavior and replicate the real flow problems. It is a fantastic development that these calibration tools and methods are now more widely available in Rocky DEM\u2019s calibration suite.\t\t\t<\/p>\n\t\t\t\t\t\t\t

Material Wizard calculations are powered by Ansys Optislang without specifically requiring an Optislang licence to use. Within seconds, the Material Wizard will provide a list of starting parameters that can be sorted by friction factor, rolling resistance, particle density or stiffness fraction. The user can then choose upto 3 material parameters and automatically create 3 new materials and particles that can then be fine-tuned using the calibration suite and efficiently calibrate the required materials.
