The new design makes it all possible. For a small company with lofty goals, using digital design optimization was a no-brainer and the only way to analyze thousands of duct designs before a single prototype was built. Designing the future with digital twinsToday, designing a new product without using digital simulation and digital twins is akin to walking into a battlefield Q-Criterion (/s^2)without armor or a weapon.
