ANSYS fluid dynamics is a comprehensive product suite for modeling fluid flow and other related physical phenomena. It offers unparalleled fluid flow analysis capabilities, providing all the tools needed to design and optimize new fluids equipment and to troubleshoot already existing installations. The ANSYS fluid dynamics suite contains both general purpose computational fluid dynamics software and additional specialized products to address specific industry applications.
The general purpose fluid analysis tools are the renowned ANSYS CFX and ANSYS FLUENT products, now also available together in the ANSYS CFD bundle. With ANSYS CFD, you have access to an unprecedented array of fluid flow physics models, allowing you to analyze your equipment with a great deal of confidence. ANSYS CFD technology is highly-scalable, allowing for efficient parallel calculations on thousands of processing cores. ANSYS CFD also includes the full-featured ANSYS CFD-Post fluid flow post-processing tool. This can be used for advanced quantitative analysis and high-quality visualizations. When ANSYS CFD is used in combination with ANSYS Mechanical it is eminently suitable to solve complex fluid-structure interaction problems.
ANSYS fluid dynamics products have a high degree of interoperability, and are designed to be fitted efficiently in your company’s Simulation Driven Product Development processes.
ANSYS CFX is a high-performance, general purpose CFD program that has been applied to solve wide-ranging fluid flow problems for over 20 years. At the heart of ANSYS CFX is its advanced solver technology, the key to achieving reliable and accurate solutions quickly and robustly. The modern, highly parallelized solver is the foundation for an abundant choice of physical models to capture virtually any type of phenomena related to fluid flow: laminar to turbulent (including transition), incompressible to fully compressible, subsonic to trans- and supersonic, isothermal or with heat transfer by convection and/or radiation, non-reacting to combusting, stationary and/or rotating devices, single fluids and mixtures of fluids in one or more phases (incl. free surfaces), and much, much more. The solver and its many physical models are wrapped in a modern, intuitive, and flexible GUI and user environment, with extensive capabilities for customization and automation using session files, scripting, and a powerful expression language.
But ANSYS CFX is more than ‘just’ a powerful CFD code: with its integration into the ANSYS Workbench platform, you benefit from superior bi-directional connections to all major CAD systems, powerful geometry modification and creation with ANSYS DesignModeler, advanced meshing technologies in ANSYS Meshing, and easy drag-and-drop transfer of data and results to share between applications (e.g. to use a fluid flow solution in the definition of a boundary load of a subsequent structural mechanics simulation). Furthermore, a native 2-way connection to ANSYS structural mechanics products allows you to capture even the most complex fluid-structure interaction (FSI) problems, in the same easy-to-use environment, saving the need to purchase, administer, or run 3rd party coupling software.
ANSYS FLUENT software contains the broad physical modeling capabilities needed to model flow, turbulence, heat transfer, and reactions for industrial applications ranging from air flow over an aircraft wing to combustion in a furnace, from bubble columns to oil platforms, from blood flow to semiconductor manufacturing, and from clean room design to wastewater treatment plants. Special models that give the software the ability to model in-cylinder combustion, aeroacoustics, turbomachinery, and multiphase systems have served to broaden its reach.
Today, thousands of companies throughout the world benefit from the use of ANSYS FLUENT software as an integral part of their design and optimization phases of product development. Advanced solver technology provides fast, accurate CFD results, flexible moving and deforming meshes, and superior parallel scalability. User-defined functions allow the implementation of new user models and the extensive customization of existing ones. ANSYS FLUENT’s interactive solver set-up, solution, and post-processing make it easy to pause a calculation, examine results with integrated post-processing, change any setting, and then continue the calculation within a single application. Case and data files can also be read into ANSYS CFD-Post for further analysis with advanced post-processing tools and to compare results from different cases side-by-side.
The integration of ANSYS FLUENT into ANSYS Workbench, provides users with superior bi-directional connections to all major CAD systems, powerful geometry modification and creation with ANSYS DesignModeler and advanced meshing technologies in ANSYS Meshing. It also allows data and results to be shared between applications using an easy drag-and-drop transfer (e.g. to use a fluid flow solution in the definition of a boundary load of a subsequent structural mechanics simulation). Combine these benefits with the extensive range of physical modeling capabilities and fast, accurate CFD results that ANSYS FLUENT software has to offer and you have one of the most comprehensive software packages for CFD modeling available in the world today.
Computational fluid dynamics (CFD) is an engineering method in which flow fields and other physics are calculated in detail for an application of interest. ANSYS uses a multidisciplinary approach to simulation in which fluid flow models integrate seamlessly with other types of physics simulation technologies. The CFD, or fluids simulation, results can be used as part of a Simulation Driven Product Development™ (SDPD) process to illustrate how a product or process operates, to troubleshoot problems, to optimize performance and to design new products.
ANSYS CFD provides access to both the well-known ANSYS FLUENT and ANSYS CFX products. Also available separately, these are the main general-purpose fluids simulation products offered by ANSYS. These two core fluids simulation solvers represent more than 1,000 person-years of research and development. This effort translates into the key benefits of fluids simulation software from ANSYS: experience, trust, depth and breadth. The CFD core solvers from ANSYS are trusted, used and relied upon by companies worldwide.
