Among the family. of CAD/CAM/CAE, CAD and CAM are more straight-forward in concept, while CAE covers a wider area and is fast developing. Now CAE has developed from numerical computation to simulation, towards a realization of virtual reality with CAE and CAD being closely combined. With the development of FEM and new artificial intelligence algorithms including ANN and GA, not only detailed designs but also global designs are supported by CAE. On the basis of a R D scheme, CAE is analyzed in terms of its target, physical content and algorithm. The application of finite-element-based and Al-based algorithms in conceptual design phase is illustrated. Advances of the modern design optimization are reviewed. The progress of CAE and some important research directions in a near future are discussed.
