What is Computational
Fluid Dynamics (CFD)?
Computational Fluid Dynamics is a powerful engineering
tool for simulating all types of fluid flows. CFD simulations produce
detailed descriptions of flow characteristics including values for
velocities, pressures, and other variables. Thermal characteristics and
other advanced physics, like chemical reactions, can also be simulated. 
Why Use CFD? CFD significantly reduces design and development time,
provides detailed information otherwise not available from physical
experiments, and quickly simulates a wide range of flow conditions. The
results are improved designs, lower risk, and shorter time to market for a
product or process. 
How does it work? CFD simulations involve solving numerically the
fundamental laws of physics, called governing equations, which
mathematically describe the properties and motion of fluids. The CFD
modeling process occurs in three fundamental steps:
