ANSYS CFX - FEA, CFD and Explicit Dynamics




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 parallelised 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 customisation 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, users 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 users 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.
