14 Jan Apply Rocky DEM to Generate More Accurate Structural Analysis
DEM is an integral tool to study particle dynamics. It handles bulk material like rocks, soil, powdered chemicals, food chips and pharmaceutical tablets.
DEM accounts for all of the forces acting on each particle within a bulk system. It then provides insight into how these materials would perform within a given component over a range of process conditions.
Rocky DEM can simulate systems with many particles that have complex shapes and accurate sizes. The tool is used across multiple industrial sectors, including:
- Heavy machinery
During simulation, Rocky DEM tracks the loads on each node of a geometry mesh. These loads are then exported as a pressure field for further analysis with Mechanical. The FEA software then discretizes the geometry and solves for the equilibrium conditions.
By coupling structural analysis with Rocky DEM, engineers can simulate transient cases while incorporating geometry motion and time-varying loads on boundary elements.
In addition, Rocky DEM is fully integrated into ANSYS Workbench so it doesn’t require external software to couple it with Mechanical. This also enables engineers to easily apply design exploration tools for virtual parametric studies, optimizations, robustness analyses and response surface generation.
Rocky DEM can replicate complex motions within its UI, including combined motion and particle-induced free body motion with 6 degrees of freedom.
