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. Interoperable with industry-leading Ansys solvers, the workflow helps engineers design highly reliable products, slash development time and win the race to market. 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 overcome this difficult design challenge, engineers require DEM, coupled with structural and fluid analysis, to assess the flow behavior of these granular particles early in the design phase. ESSS and Ansys' new workflow, Ansys Rocky, is a robust 3D DEM solution for tackling particle movement design issues. Harnessing multiple GPUs simultaneously to analyze bulk material flow systems 20-90x faster, Ansys Rocky runs high-fidelity, uncompromised massive particle models. Seamlessly integrated with Ansys® Fluent® and Ansys® Mechanical™, Ansys Rocky swiftly simulates fully coupled fluid and structural systems' bulk material movement and reaction to forces such as gravity and adhesion, ensuring new products are more reliable than ever. Unlike a traditional DEM code, Ansys Rocky accurately models particles shapes including arbitrary 3D shapes, 2D shells and flexible fiber, helping engineers quickly solve challenging design problems with very complex geometric design variations. Ansys Rocky delivers unique usability, portability, solver performance and multi-GPU acceleration to cost-effectively calculate particle transport.
