Background Analyze vibration of cars: Noise levels for comfort, quality Simulation models needed; physical prototypes not practical Detailed (huge) model needed Historically, Cray supercomputers were required: Expensive Slow job turnaround Limited benefit from analysis

Invention Description New numerical algorithm: Divide and conquer Thousands of substructures Automated multilevel substructuring (AMLS) Reduction via small substructure problems Fits into industry standard software

Benefits

Jobs run faster Cheaper computers can be used Lots of cheaper computers Analyst sees quick turnaround Broader frequency range, more analysis Better design (quieter cars) Lower cost, better product

Features

Standard code sleeps while AMLS does ?heavy lifting? and returns results Use of AMLS is transparent to user AMLS requires much less disk space & I/O Uses multiple processors efficiently Results are very accurate

Market Potential/Applications Automotive - licensed through CDH AG (Small Public Germany Co.) to: Ford, Chrysler, BMW, Saab, Mercedes-Benz, Opel, Ceat, Jaguar, Volvo, Peugeot, Honda, Nissan, Subaru, Daihatsu, Mazda, and others. New markets: Aerospace, other complex structures

Development Stage Commercial product

IP Status One U.S. patent issued: 7,188,039
