How do you implement a virtual body development process to reduce physical prototypes?

Virtual body development integrates CAE across domains: Stiffness analysis (static and modal), NVH (structural dynamics, SEA), crash (multiple modes), durability (fatigue), and manufacturing (forming, joining simulation). Implementation requires: Validated simulation methods with known accuracy, standardized model exchange formats, automated model building and analysis, correlation processes linking virtual and physical results, and decision gates based on virtual maturity. Target is eliminating early physical validation, with prototypes used only for final confirmation. Benefits include reduced development time, more design iterations, and earlier issue identification. Key enablers are model correlation confidence and compute infrastructure.
