Discrete element method (DEM) is a computational modeling framework used to simulate the behavior of granular and discontinuous bulk materials. Simulating bulk material is challenging because of the complex ways that the different discrete elements or particles interact with one another and with their surroundings. Bulk material does not exist in isolation. It often interacts with a solid structure and is embedded in a surrounding fluid. In that sense, DEM is an extension of traditional computational fluid dynamics (CFD) and finite element analysis (FEA). Granular flows are known to exhibit solid-like and fluid-like behaviors, or a combination of both.
ESSS and Ansys are collaborating to provide an improved discrete element modeling (DEM) workflow for quickly analyzing and assessing particle movement across numerous industrial applications. To help accurately and efficiently simulate these bulk motions and their interactions with fluids and structures, Ansys is introducing a new product: Ansys Rocky.
Ansys Rocky’s unmatched speed and accuracy is supported by its multi-GPU capabilities and realistic simulation of non-spherical shapes. From candy to vacuum cleaners, nearly 70% of industrial products experience bulk granular material flows, where different-sized particles with complex shapes interact, potentially impacting a product’s efficiency or structural integrity.
To accurately and efficiently overcome this difficult design challenge, engineers require a DEM solution like Rocky, which features:
