Ansys Workbench Integration

The 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 fluid dynamics software as part of an effective simulation driven product design process.

Comprehensive Physics

Ansys 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 class-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.

Class-Leading Numerics

Reliable and efficient calculations are required in order to use the fluid dynamics predictions for engineering design optimization. Ansys fluid dynamics software uses class-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.

Scalability and High-Performance Computing

The Ansys fluid dynamics computing platform is highly scalable. To solve large, industrial scale models, Ansys fluid dynamics provides powerful high-performance computing (HPC) options. Calculation speed can be increased dramatically by performing them in parallel, either on a multi-core PC, or distributed over a large computing cluster. Parallel scalability has been shown on systems with thousands of processing cores, which is unique in the industry. Ansys fluid dynamics HPC technology is the choice of leading companies worldwide.

Advanced Post-Processing

The 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.
