SOUTHPOINTE, Pa., April 22 ANSYS, Inc.(Nasdaq: ANSS), a global innovator of simulation software and technologiesdesigned to optimize product development processes, today announced that 35swimming world records have already been broken by athletes wearing a newhigh-performance swimsuit designed using engineering simulation software fromANSYS. The Speedo(R) LZR RACER(R) suit, developed for elite swimmers andlaunched in February this year, has been proven in testing to optimize swimmerperformance better than any suit to date. Seventeen out of 18 world recordswere broken at last week's FINA World Swimming Championships (25m) alone,suggesting the Speedo LZR RACER suit will make the headlines at the Beijinggames.

Software from ANSYS played a critical role in the development of the suit.The technology was used to predict fluid flows around the body of an eliteswimmer in the outstretched glide position (assumed immediately after theinitial dive and following each lap's turn off the pool wall) to identifyareas where drag, and its slowing effect, is likely to occur. In addition, thesimulation analysis guided placement of specially designed drag-reducingSpeedo LZR RACER panels to minimize this negative effect. Simulations thenwere run to confirm the Speedo LZR RACER suit was effective in reducing dragand enabling athletes wearing the suit to swim faster than ever before.

"While never forgetting the endless dedication and spirit of world-classathletes who continually hit new heights, we are thrilled with the success todate of the Speedo LZR RACER suit. This is clear evidence of the power ofapplying advanced engineering simulation technology to optimize all of thedesign metrics of a product. The groundbreaking innovation represented by thedesign of the Speedo LZR RACER suit could not have been achieved without thedepth and breadth of technology from ANSYS," said Jim Cashman, president andCEO of ANSYS, Inc. "From the ANSYS perspective, we're finding that therereally are no barriers to the potential applications and industries in whichour software can be crucial to competitive advantage."

"Speedo is a world-class brand dedicated to continual innovation andworking with the best, which makes ANSYS a perfect partner for us. The use ofANSYS software was an integral part of our design and development process,which, alongside with our other key partners, resulted in the development ofthe world's fastest swimsuit, the Speedo LZR RACER," said Jason Rance, head ofSpeedo's Aqualab research and development group.

ANSYS worked with Dr. Herve Morvan of Nottingham University and OptimalSolutions in conducting the computational fluid dynamics (CFD) research usedto develop the Speedo LZR RACER suit. Speedo has long been recognized as theworld's leading swimwear brand.
