Cray and MCube team to attack automotive wind noiseMarseille 25 Oct 2000 Cray and MCube, a simulation software provider to manufacturers worldwide, will collaborate on next-generation automotive design, alleviating wind noise from side mirrors and driver's side window structures (`"A-pillars"), as well as exhaust system noise. The goal of the supercomputing collaboration is to help automakers to increase passenger cabin comfort.
Simulation combining powerful software and supercomputers already has made vehicles safer in crashes and far more efficient, but even makers of expensive luxury cars cannot accurately predict wind and exhaust noise (aeroacoustics).
"Accurate simulation of aeroacoustics requires a new generation of sophisticated software and unprecedented computing power", stated Dimitri Nicolopoulos, director of MCube. "MCube has been developing the next-generation software for several years and is ready to demonstrate its industrial feasibility. We believe the processing power of the Cray SV1 supercomputer will enable a breakthrough."
"Simulating side mirror noise will be our first target, for several reasons", stated Cray Inc. applications manager Jef Dawson. "First, it is one of the main sources of airflow-related noise. Second, there is good experimental data to validate our computer simulations against, to ensure that the simulations are effective engineering tools. Third, it requires very powerful processors (CPUs), and Cray supercomputers have those. Most important, it will allow automakers to
speed time-to-market and save money by reducing physical prototyping."
"MCube and its parent firm, Mecalog Holding SARL, are among the world's most respected software companies", added Mr. Dawson. "MCube has leading-edge experience in the established field of computational fluid dynamics (CFD) and superb credentials for addressing the
important new domain of computational aeroacoustic analysis (CAA)."
