Simulation-Based Design is a method that uses computer simulations to create and test designs before they are built. This approach allows designers and engineers to visualize how a product will perform under various conditions, helping them identify potential issues early in the development process. By using virtual models and simulations, teams can experiment with different materials, shapes, and configurations without the cost and time associated with physical prototypes. This leads to more efficient design processes, improved product quality, and reduced development costs, ultimately resulting in better products that meet user needs.
