CAE

Computer-aided engineering (CAE) refers to the use of computer-based methods and software to support engineering analysis, simulation, and optimization of products and processes throughout the design, development, and manufacturing lifecycle.

Core CAE tools perform finite element analysis (FEA), computational fluid dynamics (CFD), multibody dynamics (MBD), thermal and electromagnetic simulations, and optimization. They often operate on CAD models, importing geometry and mesh generation, solving complex equations, and producing results such as stress, deformation, flow fields, heat transfer, frequency responses, and reliability indicators.

CAE workflows typically integrate with computer-aided design (CAD) systems to form a design-validate loop, and may use high-performance computing and cloud resources. Post-processing involves visualization, data interpretation, and validation against experiments. Modern CAE also encompasses multiphysics, uncertainty quantification, and surrogate modeling to accelerate design exploration.

Applications span aerospace, automotive, mechanical, civil, energy, electronics, and consumer products. Common tasks include structural analysis and crash simulations, aerodynamic performance, thermal management, vibroacoustic, and reliability assessment.

History: CAE emerged in the late 20th century with advances in finite element methods and integrated CAD/CAE environments; over time tool suites became more multidisciplinary and capable, enabling digital twins and design optimization.

In other contexts, CAE may refer to the Certified Association Executive designation, or to CAE Inc., a Canadian company that designs and manufactures simulation equipment.
