What is computer-aided engineering (CAE)?

Computer-aided engineering (CAE) is the entire engineering process from product design ideation and drafting to simulation and analysis testing. CAE involves the practice of applying computer assisted, math-based analysis and simulation techniques to the product development process. CAE combines computer aided design (CAD) with disciplines such as finite element analysis (FEA), computational fluid dynamics (CFD), multi physics, and engineering calculations. CAE aims to create products, assemblies, and component parts that are not only validated to survive their operating conditions but also optimized for desired characteristics like weight and strength.

Design Better


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.

CAE Prototypes and testing

Prototypes and testing

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.

Great efficiency with CAE


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.

Design optimization with CAE


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.

Applications of computer-aided engineering

Finite element analysis (FEA)
Computational fluid dynamics (CFD)
Simulation and Analysis

Finite element analysis (FEA)

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.

Computational fluid dynamics (CFD)

Computational fluid dynamics allow you to model digital fluids in your CAD system and save on hardware prototyping costs. With the use of numerical analysis, you can study and visualize the flow of fluids in real life.


Improve quality, lead time, and costs by using CAM software that gives you the highest quality precision machining in the fastest possible time. Increase productivity and toolpath designs with more efficient machining and tooling of sheet metal along with additive manufacturing.

Simulation and Analysis

You need to test the stresses and loads under which your product will operate in the real world to design the best product possible. Creo offers you design guidance and a comprehensive set of simulation capabilities that allow you to analyze and validate the performance of your 3D virtual prototypes.
