Designing on the Fly, Testing in the Cloud.

Product design and simulation, once largely bifurcated into two separate worlds, are blurring into one with the help of large-scale cloud computing.

Volkswagen, processor producer NVIDIA (, simulation firm Altair ( and Amazon Web Services got together to demonstrate how form and function are merging to design more fuel-efficient vehicles. Specifically, Altair developed a computational fluid dynamics (CFD) application using NVIDIA GPUs (graphic processing units) running on Amazon Web Services' cloud. Those big interfaces enabled VW to test and predict the aerodynamics of a variety of Jetta designs in multiple simulations.

"We were able to run 200 car shape variants in a time frame that would normally correspond to only a few runs with our current operational tools," said Henry Bensler, head of computer-aided engineering (CAE) at Volkswagen Group Research

With a GPU-based system, Volkswagen could save up to 70 percent of its hardware costs, according to Altair, while rapidly speeding up design cycles.
