Computer-Aided Engineering (CAE) is a sophisticated technology that leverages computer software to simulate, analyze, and optimize engineering designs and processes. It enables engineers to create virtual models of products, perform complex simulations such as stress analysis, fluid dynamics, and thermal behavior, and predict real-world performance without building physical prototypes. By integrating CAE tools, industries like automotive, aerospace, and manufacturing can accelerate innovation, reduce costs, minimize errors, and enhance product reliability through iterative testing and data-driven decision-making. This field encompasses various applications, including finite element analysis (FEA), computational fluid dynamics (CFD), and multi-body dynamics, making it an essential component of modern engineering workflows.
