Get Creo today for a single comprehensive suite of integral solutions supporting CAD, CAM, CAE, and CAID
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.
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.
