A model, no matter how refined, tells only part of the truth. The answer might be articulated along the following lines: Plus, huge compute power is needed to run such models in acceptable periods of time.īut does this growth of model size and bandwidth really pay off? Is it really possible to build safer cars by building larger and more sophisticated computer models? Are there any intrinsic limitations to crashworthiness of automobiles, dictated by the physics involved, which make it impossible to improve performance beyond today’s already high standards? The size and cost of computer models for car-crash analysis is steadily growing - models with millions of finite elements are common. Simulating a car crash with a computer is one of the most demanding tasks performed by engineers in the automotive industry. Every crash test is unique - the chaotic nature of a crash can never be a repeatable event.
