The popular fluid dynamics products from ANSYS are 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.
Connectivity to other ANSYS products enables new simulation avenues. Ties with ANSYS Mechanical, ANSYS Maxwell and other ANSYS technologies delivers the capability to model multiphysics applications such as fluid–structure interaction (FSI). The connection with the ANSYS DesignXplorer tool permits advanced design optimization.
ANSYS Workbench enables fluid dynamics to be included in an effective simulation-driven product design process.
Fluid dynamics software from ANSYS 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.
ANSYS fluid dynamics technology excels at turbulent flow modeling, with an industry-leading suite of turbulence models covering even the most complex flows. 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.
Reliable and efficient calculations are required to use fluid dynamics predictions for engineering design optimization. ANSYS fluid dynamics software uses industry-leading numerics to solve 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. The technology includes finite-volume solvers using both coupled and segregated methods for general fluid flow modeling as well as 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.

Fluid dynamics technology from ANSYS provides powerful and scalable high-performance computing (HPC) options. Parallel processing with ANSYS CFD HPC allows consideration of higher-fidelity CFD models — including more geometric detail, larger systems (such as a full 360 degrees blade passage rather than a single blade passage), and more complex physics (for example, 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 by revealing design issues that might lead to product failure or troubleshooting delays. Confidence in a design can be improved by using HPC to understand detailed product behavior.
ANSYS CFD HPC increases throughput by speeding up turn-around time for individual fluid dynamics simulations. This enables engineers and designers to consider multiple design ideas and make the right decisions early in the design cycle. Using ANSYS CFD HPC can make an engineering staff and product development process more productive and efficient.
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 easy to use, and it works exceptionally well from multi-core desktop workstations to high-end HPC clusters. Linear scalability has been shown on systems with more than 1,000 processors, an achievement unique in the industry.
The common post-processor for ANSYS fluid dynamics software is. This tool provides advanced quantitative and high-quality 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 cases 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.
Smart engineering requires customizing workflow and modeling processes. ANSYS fluid dynamics software offers multiple customization options. Special physics models can be implemented, or solution variables and boundary conditions can be defined when needed. To ensure established best practices are followed, input panels can be defined that contain application- or company-specific terminology. By using scripting functions, model setup, analysis and reporting can be automated within ANSYS fluid dynamics software. Furthermore, these functions can be combined with ANSYS Workbench (project-wide) scripting tools that go beyond fluid dynamics itself. Using scripting tools for parameter/file/data management as well as design exploration studies can increase productivity.
