Computational fluid dynamics (CFD) is an aspect of multiphysics system analysis that undertakes simulating the behavior of fluids and their thermodynamic properties using numerical models.
In engineering, CAE simulation plays an increasingly powerful role in product design. But the factor limiting its more explosive growth is the reliance in many of the disciplines on experts and analysts. There is certainly a desire to be able to democratize at least a subset of the CAE simulation areas and broaden the pool of engineers that can effectively conduct these analyses and benefit from the more immediate performance feedback of their designs.
Engineering Simulation is used in many industries such as Aerospace, Oil & Gas, Automotive, Electronics Design to make critical decisions while saving money. For the Data Center industry, it predicts airflow and temperature distribution regardless of the status of the site.

Computational fluid dynamics (CFD) can be used to influence decisions early in the design process. In order to assess the state-of-the-art of CFD and its predictive capability for medical devices, the U.S. Food and Drug Administration (FDA) developed two benchmark models for validation.
The traditional CFD process hasn't changed in 30 years, and the bulk of CFD done today (as much as 80% we estimate) complies with this accepted norm of creating a geometry in CAD, exporting it to a meshing tool, meshing it, setting up and running a CFD solver, post-processing results, going back into the geometry, altering it and continuing to do these design loops again and again.
CFD simulates the flow of liquids and gases by performing millions of numerical calculations. CFD analysis is typically carried out earlier in the design process even before the first prototype is made. With high-speed supercomputers, better designs can be achieved quicker, faster, and cheaper. Multiphysics is advanced CFD involving multiple physics coupled to mimic the real behavior as accurately as possible.
