Computational fluid dynamics (CFD) is an engineering method that calculates flow fields and other physics 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 process — to illustrate how a product or process operates, to troubleshoot problems, to optimize performance and to design new products.
