Relative displacement between them may produce linear and angular deformations of the bonds, leading to bending and flexing of the fibrous material.Das "Wiring" könnte etwas besser sein, gerade dann, wenn die Leitungen über andere Bauteile verlaufen (das ist manchmal nervig), aber der Farbwechsel bei den Ein/Aus-Zuständen ist gut gemacht.ĭazu würde ich gerne wissen, wie ich den Arbeitsbereich (die Fläche) vergrößern kann, da mir dieser viel zu klein ist.Įigene Objekte (mit den Sample-Bauteilen als Referenz) würde ich auch gerne schreiben, doch weiss ich nicht, welche Anweisungen der Compiler alle versteht (also welche C++ Version bzw Java usw), da sind mir auch die maximalen 10 Eingangs- und 10 Ausgangs- Pins zu wenig. Flexible Fibersįlexible fibers can be simulated by connecting aligned sphero-cylinders by means of virtual bonds, which have elastic and viscous properties. Rocky offers several different adhesive force models to replicate the different adhesion situations that wet bulk materials encounter in different applications. Wet materials have the added complexity of cohesion/adhesion, which Rocky captures by modeling the adhesive force as a function of the stress and scaling it with the contact force. Rocky can handle both dry and wet bulk materials.

This approach enables to accurately capture shape-dependent breakage and crack propagation. Rocky’s unique discrete breakage model preserves mass and volume of the complex particle shapes considering the collision location at the particle’s surface along with its consequent internal stresses. Either use Rocky’s default shapes or define and import your own custom shapes, including fibers and shells, both rigid and flexible. You can mix and match different shape, size, flexibility, and adhesion combinations to create your own unique particle sets. Rocky enables you to simulate a system with real particle shapes and sizes, specifying both round and truly non-round particle shapes. By coupling Mechanical with Rocky, engineers can simulate transient cases while incorporating motion of parts and time-varying loads on boundary elements. Two-way is when the fluid flow affects the motion of the particles and the particles in turn affect the motion of the fluid.įor FEA-DEM simulations, geometry loads from Rocky are passed to Ansys Mechanical to evaluate structural stresses. One-way is when the fluid field affects the particle flow, but the particles do not affect the fluid flow. There are two methods for CFD-DEM simulations: one-way or two-way coupling. Rocky is integrated into the Ansys Workbench environment and couples seamlessly with Ansys Fluent and Ansys Mechanical for CFD-DEM and FEA-DEM simulations. Rocky offers industry leading models to get you the most accurate answers. Below, you can see the flow chart for the DEM algorithm.Īnsys Rocky’s Advanced Modeling Capabilitiesĭifferent modeling capabilities are needed to accurately describe and predict particle-level phenomena. The most important consideration for ensuring a high-fidelity simulation is to account for all the relevant forces acting on each particle. Rocky is a mesh-free method that solves Newton’s Second Law of Motion for each element/particle. Some of these I touch on in more detail below. Unique customization and automation APIs.Ěccurate particle physics including breakage.Ĝomplex particle shapes including flexible fibers and shells.To accurately and efficiently overcome this difficult design challenge, engineers require a DEM solution like Rocky, with industry leading features, including: 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 help accurately and efficiently simulate these bulk motions and their interactions with fluids and structures, Ansys is introducing a brand-new product: Ansys Rocky.Īnsys Rocky is the fastest, most realistic DEM simulation product on the market. Granular flows are known to exhibit solid-like and fluid-like behaviors, or combination of both. In that sense DEM is an extension of traditional computational fluid dynamics (CFD) and finite element analysis (FEA). Bulk material does not exist in isolation: it is often interacts with a solid structure and is embedded in a surrounding fluid. 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. Discrete element method (DEM) is a computational modeling framework used to simulate the behavior of granular and discontinuous bulk materials.
