Jaguar Land Rover Ltd. is increasingly using digital prototypes and computer-aided design tools to reduce costs and speed the development process, Automotive News Europe reports.
Computational fluid dynamics programs are often cumbersome and erratic, which limits their usefulness. Exa Corp. claims its PowerFLOW aerodynamics software eliminates these problems, and creates a simulation tool that not only replicates wind tunnel testing, but accurately models airflow.
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).
