In recent years the concept of simulation-driven design has gained significant popularity. Design-embedded simulation tools help companies verify their designs without relying on consultants or expensive, difficult to use packages of yesteryear that were the status quo not too long ago. When parts can be validated early in the design process, the business value is obvious; a few clicks of the mouse and manufacturers are reducing prototyping costs and cycle time to market.
Well, maybe it takes more than a few clicks of the mouse, but the point is that design simulation tools have reshaped how the engineering and product design communities approach product design and consequently, product development. The truth is that most of these tools are still really design driven simulation. Where analysis is done to check an existing design to validate "hunches", "hand calculations" or "tribal knowledge".
