This video explores the evolution of CAD and the role of simulation in modern design. It explains why simulation adoption lags behind CAD, citing cost, complexity, and perceived need for expertise. SOLIDWORKS addresses these challenges with integrated, easy-to-use tools for structural analysis, fluid dynamics, plastics, and motion studies. Examples include fatigue testing for Renthal bike components and thermal management for electronics using flow simulation. The video demonstrates static and fatigue studies, topology optimization for lightweight designs, and parametric optimization for heat sinks. For advanced non-linear problems, SOLIDWORKS offers Simulation Professional Engineer powered by SEMULEA, enabling cloud-based high-performance computing. Overall, simulation reduces prototyping costs, improves performance, and drives innovation.
