Tel.: +1.248.614.2400, ext. 464 email@example.com Leading automotive OEM using advanced HyperWorks CAE technology to replace physical testing with virtual simulation TROY, Mich., (Oct. 22, 2007) – Altair Engineering, Inc, a leading global provider of technology and services that empower client innovation and decision-making, announced today that PSA Peugeot Citroën, one of the leading European automotive original equipment manufacturers (OEMs), has selected Altair’s RADIOSS simulation solution for crash simulation and analysis. RADIOSS, a nonlinear finite-element solver, is part of Altair’s HyperWorks computer-aided engineering (CAE) software suite. “The performance and code quality of the CAE tools we use are very important to us,” said Laurent Di Valentin, head of Numerical Simulation, PSA Peugeot Citroën. “HyperWorks tools, especially RADIOSS, deliver the quality and performance we expect and need in our CAE processes. Using RADIOSS, we can simulate very large models and can perform a complete vehicle simulation – from model building up to crash simulation – in the same environment. We have been able to replace many physical tests with RADIOSS’ numerical simulation, saving time and money in the development phase while delivering the same or even higher level of quality.” RADIOSS is a comprehensive transient, dynamic finite-element solver for simulating impact, safety-related performance, manufacturing processes and fluid-structure interaction problems. From consumer product drop-testing to vehicle crash analysis, terminal ballistics to explosions, RADIOSS provides a world-class solution to solve today's most complex physical problems. “We are proud to consider PSA Peugeot Citroën one of our most important customers in France,” said Mauro Guglielminotti, managing director of Altair Engineering France. ”Especially within the automotive industry, crash simulation is gaining importance. Physical testing is expensive and time-consuming. With RADIOSS, automotive OEMs such as PSA Peugeot Citroën can improve their development processes and shift their testing efforts from the physical into the virtual world.” About PSA Peugeot Citroën PSA Peugeot Citroën is a world-class automobile manufacturer, supported by two broad line marques, Peugeot and Citroën, and the expertise of its employees.
