Software Update
something that is prohibitively expensive with prototype builds and physical tests. Advanced simulation methods ex- ist to allow a car manufacturer to simulate the aerodynamic performance of a vehicle in less than one hour with high- performance computing. Powertrain design modifications are central to the effort
Simulations offer automotive engineers key input on aerodynamic performance of new designs.
ducing a stylish vehicle. Thanks to simulation, it’s possible to analyze several hundred body shape design variations,
to improve fuel economy and help meet the 54.5 CAFE standards. Simulation software is fundamental to the de- velopment of turbochargers and superchargers, which are being utilized more and more in engines to increase fuel ef- ficiency. Simulations allow engineers to design the fine blade structures that spin at extremely high speeds, force feeding a smaller, more fuel-efficient engine that consumes less fuel. Simulation software has a greater role to play in the devel- opment of new electric powertrains for hybrid and electric vehicles than in any of the other traditional vehicle systems. This is because a large amount of engineering development is needed for these new innovations that involve systems
