This paper describes a novel automated computer-aided engineering (CAE) system for multidisciplinary structural design. An automatic finite element (FE) mesh generation technique, which is based on fuzzy knowledge processing and computational geometry techniques, is incorporated into the system, together with a commercial FE analysis code and a commercial solid modeler. The system allows fully automated FE analyses of various physical phenomena, i. e., electrostatic analysis, stress analysis, modal analysis and so on, to be performed. An optimum design solution and/or satisfactory solutions are then automatically searched for using the genetic algorithms modified for a real search space, together with the automated FE analysis system. This CAE system is successfully applied to the shape design of a microaccelerometer based on a tunnel current concept.
