BMW SAUBER F1 TEAM RACES TO FRONT WITH FLUENT CFD.

ANSYS, Inc. (NASDAQ:ANSS), Southpointe, Pa., a global innovator of simulation software and technologies designed to optimize product development processes, has announced that ANSYS engineering simulation software assisted the BMW Sauber F1 Team, who has more than double last year's points total in the 2007 Constructors' Championship.

Prior to the season, the BMW Sauber F1 Team signed an extended agreement with Fluent Deutschland, a subsidiary of ANSYS, Inc., to use FLUENT(R) computational fluid dynamics (CFD) software to run powerful engineering simulations on its new supercomputer -- one of the largest in Europe -- rather than invest in a second wind tunnel. This investment in CFD has allowed the team to run increasingly complex simulations of race car aerodynamics, far quicker than was previously possible. This has enabled the BMW Sauber F1 Team to analyze and implement design changes more quickly, which combined with other advances the team has made, has delivered the team's best performance in the Constructors' Championship to date.

"The launch of our latest supercomputer was a decisive reinforcement of our CFD capacity. Unlike other teams, we didn't plan to build a second wind tunnel. Instead, we have used the key relationship commitment with ANSYS to continue to develop and exploit the expanding potential for CFD that high- performance computing gives us," explained Mario Theissen, BMW Motorsport Director. He added that wind tunnel testing will continue as an important design element of their F1 racing car design because of validation of results and other areas of car development.

"The big difference with CFD compared to wind tunnels is that you not only get results, but also get an understanding of what goes on. Wind tunnel testing remains important with experimental work and CFD complementing each other," Theissen said.

To optimize the performance of the FLUENT CFD software, the BMW Sauber F1 Team invested in a custom-built supercomputer called "Albert2," the successor to its original Albert supercomputer developed in 2004. Powered by 512 Intel(R) Xeon(R) 5160 dual core processors, Albert(2) is 5.5 times more powerful and three times faster than the first Albert computer. Albert2 was specifically designed and built to run CFD simulations using the latest version of FLUENT software. It has the capacity to make 12,288,000,000,000 calculations per second, which highlights the staggering pace of advance in the potential power available to perform CFD simulations. Theoretically, the BMW Sauber F1 Team could run simulations approaching and even exceeding the landmark figure of 1 billion cells. When FLUENT became the first CFD software tool to be used in F1 -- by the Benetton team of 1992 -- simulations of only 100,000 cells were possible, such as the analysis of a front wing. The possibility of FLUENT meshes of 1 billion cells or more demonstrates how the continued partnership between the BMW Sauber F1 Team and ANSYS is proving critical to driving CFD development and making the technology ever-more important in the design process.

"Working together with the BMW Sauber F1 Team, we are exploring how maximum benefit can be yielded in aerodynamic design," said Ferit Boysan, vice president and general manager at ANSYS, Inc. "Relationships such as this are genuinely pioneering the engineering simulation possibilities of the future, and they could well have implications far beyond F1 racing. We are working at the leading edge of the technology, with the exciting thing being that we don't even know what the limits are yet."

Computer-aided engineering and CFD simulations can be applied to many areas of the racing car, allowing team engineers to quickly and accurately test a number of design candidates before developing only the most promising for wind tunnel testing. The new compute power offered by the Albert2 supercomputer allows full-car simulations in addition to the aerodynamic testing of components such as the front and rear wings, turning vanes, brake ducts, fuel tanks and more.

About the BMW Sauber F1 Team

The BMW Sauber F1 Team is a Formula One racing team with bases in Munich, Germany and Hinwil, Switzerland. The team came into existence on January 1st 2006 following the purchase of a majority share of the existing Sauber Formula One team by German car manufacturer BMW. For its first season in 2006, the team scored two podium finishes and placed fifth in the Constructors' Championship. The BMW Sauber F1 Team continues to use the facilities in Hinwil, mostly for chassis construction and improving aerodynamics, while BMW's headquarters in Munich is responsible for designing and building the entire powertrain and electronics. The BMW Sauber F1 Team has been using the FLUENT software tool from ANSYS, Inc. for its racing car design and development since 2001.
