The field of CFD has grown by leaps and bounds and is no longer the realm of the few. In 2008, I created a CFD group on LinkedIn, there were 6 of us. Today that same LinkedIn group boasts more than 44,000 members.
The tools have evolved significantly over the years too. Not long ago, companies evaluated models using “in-house” packages made of disjointed programs with scant documentation and hard-to-find training support. As you can imagine, it was not easy to use—engineers needed expert knowledge of mathematics and computational methodologies to develop, modify, and apply these codes for their own use.
Fortunately, organizations today can now take advantage of commercial and even open source tools that they can embed into their design and R&D processes.
