Computational fluid dynamics (CFD) is an engineering tool to simulate the action of thermo-fluids in a system. It uses data structures to solve issues of fluid flow like velocity, density, and chemical compositions.

CFD allows one to visualize the invisible. It can quickly iterate and optimize a design to achieve performance levels that wouldn’t be possible with manual calculations. Carrying out CFD to predict the function of key design elements at an early stage reduces risks that would otherwise persist until later stages where change is more costly.
