CyDesign is developing a physics-based modeling system that will let the engineer quickly assess design options against requirements during the conceptual design stage. Should the vehicle have conventional or hybrid drive? How will thermal loads affect an implanted medical device? By providing answers to these questions early in the design, a more robust and reliable system will be built. CyDesign Studio will help the engineer gather requirements, keep them pertinent to the design, explore the trade space of possible design alternatives, assess the viability of these alternatives, and provide guidance resulting in a much better final product.
