Daimler Mercedes-Benz has been using simulation in R&D for around 50 years. What started as in-house developed solutions for vehicle design eventually evolved, and the use of more detailed models has made high-performance computing (HPC) a necessity.<\/P><\/p>\n

\"NVH<\/span>\ufeffToday Mercedes-Benz runs more than 400 full-vehicle jobs a day for NVH \u201cwhere one run involves calculating 8,000 modes from a 30 MDOF matrix,\u201d says Dr. J\u00fcrgen Kohler, head of NVH CAE and Vehicle Concepts at Daimler AG.  Those large simulation demands require powerful compute clusters and software to handle them.<\/P><\/p>\n

Equally important is the time it takes to get results back from the analyses. \u201cIn the past, we had to wait several days,\u201d says Dr. Kohler. \u201cToday we are able to obtain results overnight.\u201d<\/P><\/p>\n

Mercedes-Benz uses NX Nastran for NVH and structural analysis<\/A>, while LMS Virtual.Lab <\/A>handles chassis simulations.<\/P><\/p>\n

Between the sheer magnitude of the simulations and the need for faster turnaround times, it\u2019s obvious why Mercedes-Benz requires high-performance computers for their CAE analyses. More powerful computers equate to \u201cmore robust simulations, more optimization runs, and more detailed models,\u201d Dr. Kohler says. And all of those elements make for better quality cars.<\/P><\/p>\n

The company realized early on the importance of simulation-driven design for designing increasingly complex vehicles in a reasonable amount of time. \u201cToday CAE has become an indispensable part of modern development processes for us,\u201d Dr. Kohler says. \u201cOur so-called \u2018Digital Prototype\u2019 has been integral to the work of Mercedes-Benz Cars Development for over a decade now.\u201d<\/P><\/p>\n
