ANSYS Workbench IntegrationThe main ANSYS fluid dynamics software is fully integrated into the ANSYS Workbench environment. The ANSYS Workbench platform offers efficient and flexible workflows, CAD associativity, and powerful capabilities in geometry modeling and meshing. The built-in parameter manager makes it easy to conduct design exploration. The connectivity to other ANSYS products enables new simulation avenues. Connections with the ANSYS Mechanical software and other ANSYS technologies lets users model multiphysics applications such as fluid-structure interaction (FSI). The connection with ANSYS DesignXplorer provides advanced design optimization. ANSYS Workbench enables the inclusion of fluid dynamics in an effective simulation-driven product design process.
Comprehensive physicsANSYS fluid dynamics software offers unparalleled breadth and depth in the modeling of fluid flow related physics phenomena. Viscous and turbulent, internal and external flows can be calculated with ease. In fact, ANSYS fluid dynamics technology is a leader in turbulent flow modeling, with a industry-leading suite of turbulence models covering even the most complex flows. The turbulent flow predictions can be extended to flow induced noise predictions. Heat transfer with and without radiation can be modeled. ANSYS fluid dynamics software has long been a leader in modeling multiphase flows, chemical reaction, and combustion.
Industry-Leading NumericsReliable and efficient calculations are required in order to use the fluid dynamics predictions for engineering design optimization. ANSYS fluid dynamics software uses industry-leading numerics to solve the fluid flow equations. A variety of solver methods and numerical schemes are available to ensure that the calculations are both efficient and result in accurate predictions. This includes finite-volume solvers using both coupled and segregated methods for general fluid flow modeling, and a finite-element solver for viscous flows of complex fluids. Fully unstructured grids can be used with all common cell-types, including polyhedral meshes. Solution based mesh adaption can be used to further improve prediction accuracy.
Powerful and Scalable High-Performance Computing CapabilitiesANSYS fluid dynamics provides powerful and scalable high-performance computing (HPC) options. Parallel processing with ANSYS CFD HPC allows you to consider higher-fidelity CFD models – including more geometric detail, larger systems (e.g., a full 360 degrees blade passage rather than a single blade one), and more complex physics (e.g., an unsteady turbulence rather than a steady turbulence model). The result is enhanced insight into product performance – insight that can’t be gained any other way. This detailed understanding can yield enormous business benefits – revealing design issues that might lead to product failure or troubleshooting delays. Using HPC to understand detailed product behavior, you can gain confidence in your design and ensure that your product will succeed in the market. ANSYS CFD HPC also increases throughput by speeding up turn-around time for individual CFD simulations. This enables you to consider multiple design ideas and make the right design decisions early in the design cycle. Using ANSYS CFD HPC you therefore make your engineering staff, and your product development process, more productive and efficient. The ANSYS CFD technology incorporates optimization for the latest multi-core processors and benefits greatly from recent improvements in processor architecture, algorithms for model partitioning, combined with optimized communications and load balancing between processors. ANSYS CFD HPC is trivial to use, and works exceptionally well from multi-core desktop workstations to high-end HPC clusters. Linear scalability has been shown on systems with more than a thousand processors, which is unique in the industry!
Advanced Post-ProcessingThe common post-processor for the ANSYS fluid dynamics software is ANSYS CFD-Post. This provides for advanced, quantitative, and visual post-processing capabilities. ANSYS CFD-Post lets users generate analysis reports with ease. The reports support regular bitmap images or 3-D viewer files, data tables, annotations, x-y charts, and histograms. Results of different simulations can be easily compared with the new case comparison and difference plot functionalities. ANSYS CFD-Post is especially suitable to process transient data sets, making it easy for users to create animations of their time-dependent results.
Customization & Project-wide ScriptingSmart engineering requires that you can customize your workflow and modeling processes. The ANSYS fluid dynamics software offers multiple customization options. You can implement your own special physics models or define your own solution variables and boundary conditions when needed. You can define input panels that contain your application- or company-specific terminology, to ensure established best practices are followed. By using scripting functions, model setup, analysis, and reporting can be automated within the ANSYS fluid dynamics software. Furthermore you can combine these functions with Workbench (project-wide) scripting tools that go beyond fluid dynamics itself. In this respect, you can significantly increase the productivity by using the scripting tools for your parameter/file/data management as well as design exploration studies.
