3D CAD World - Move from wind tunnel testing to simulation-driven design offers typical automakers more than 500% ROI

Moving from wind tunnel testing of physical prototypes to simulation-driven design processes can offer typical automotive OEMs more than 500% ROI (return on investment), according to research from Tufts University’s Gordon Institute for engineering management.

In a project sponsored by CFD software developer Exa Corp., the Tufts team analyzed the cost-benefit of deploying digital prototyping and simulation software to replace the physical prototypes and test procedures conventionally used in design, development and validation of vehicle aerodynamics, thermal management and aeroacoustics.
