Engineers analyze just about every type of product development and research effort imaginable. Analyzing machine designs, injection molded plastics, cooling systems, products that emit electromagnetic fields, and systems that are influenced by fluid dynamics are just some examples of how companies leverage design analysis.
In the field of mechanical engineering, design analysis can solve a wide range of product development problems. Engineers can use design analysis to predict the physical behavior of just about any part or assembly under any loading conditions: from a simple beam under a bending load to car crash simulations and vibration analysis of aircraft. The true power of design analysis is the ability to perform any of these types of studies accurately without building a single thing. All that is needed is a CAD model.
