Automotive Design and Production - Follow the Bouncing (CFD) Balls

While it may seem as though this picture shows a Chrysler 200 being surrounded by some sort of colorful bouncing balls, an automotive analog to one of those ball pools found in fast food joints. . . in point of fact, this is an aerodynamic simulation of the sedan being run in PowerFlow, a software package from Exa Corp. that allows designers and engineers to see things on a vehicle that are not readily apparent through wind tunnel testing (e.g., airflow within wheel wells).
