Computational Fluid Dynamics, or CFD, is the science of using numerical methods and computers to solve a set of partial differential equations to quantitatively predict fluid flow or heat transfer in an application. It is used in a variety of fields, from aero/hydrodynamics to energy, combustion, environmental flows, biomedical engineering and many more. Using CFD simulations significantly reduces the number of design prototypes required, saving considerable time and money in the design process - accounting for its rising importance in R&D. There are numerous CFD software packages, both commercial and open-source (free), the suitability of each based on the user’s knowledge, budget, and intended application. This presentation will provide an overview of some of the most popular CFD packages, their capabilities, and pros and cons, to help you choose the one that will work best for your company.
