The benefits of CAE primarily revolve around the reduction of prototyping and testing which can be costly, along with increasing the efficiency of the design process. The greatest benefit of using CAE, however, is that it allows designers and engineers to optimize their designs to create the best product possible within the design specifications.
By incorporating simulation into the design process, organizations can streamline their workflows. This eliminates the unnecessary sequential design and analysis iterations of traditional siloed companies. With CE, teams spend less time designing and more time engineering.
Organizations that lack the resources or people to perform CAE compensate by over-engineering their products. For example, they use more durable materials, increase wall thicknesses, add structural members, and incorporate more fasteners. These methods add weight and cost to the product, but by using CAE you can optimize the designs to remove the added weight.
CAE is not a substitute for prototypes and testing. Instead, it provides a high level of confidence that you perform the right tests and that your product should survive its operating environment.
Finite element analysis is used to predict how a model will react to forces in the real world—sort of like a digital prototype. This analysis is part of the product design cycle that examines the effects of forces such as heat, vibration, and much more on a designed model.
