Rocky DEM quickly and accurately simulates the flow behavior of bulk materials with complex particle shapes and size distributions.
Rocky DEM is fully integrated with the Ansys Workbench™ suite of products, allowing engineers to perform various coupled analyses of particle simulation together with other physics such as structural, fluids, and thermal modelling. Making use of this integration enables you to reduce the costs associated with design iteration. By linking together Rocky with other Ansys software, Workbench saves you time by automatically transferring data between the programs and automatically updating linked projects based upon the results calculated.
In Rocky DEM can you combine the processing power of several GPU cards to accelerate your simulations, enabling you to work with higher volumes of data in less time.
Advantages of Rocky DEM
Rocky DEM’s unique ability to utilize one or more GPU (Graphics Processing Unit) cards on the same motherboard greatly speeds up the computational time and also allows for large-scale simulations involving tens of millions of particles.
Rocky DEM allows you the freedom to configure complex geometry movements by enabling you to set up as many translations, rotation, vibration, swinging, crushing, and free-body motions—and combinations thereof—as you desire within your simulation.
Two kinds of breakage models are available in Rocky DEM: The Ab-T10 model and the Tavares model. Both models preserve mass and volume.
Rocky DEM enables you to collect and analyze energy spectra as a useful alternative to the often computationally intensive breakage modelling solutions.
Rocky DEM also can be used also as a tool for the preparation of abrasive wear of solid surfaces and there are two major ways you can use Rocky DEM to gain an understanding of how your geometries will wear over time.
The visualization of collision statistics is a key feature in Rocky DEM. During the simulation, relevant collision data is stored between two consecutive output time levels.
Turning on Thermal Modeling enables you to simulate conductive heat transfer from particles to other particles, and from particles to boundaries. When used with CFD Coupling methods, it can also simulate convective heat transfer between particles and fluids.
