Data Exchange Between CAD and Finite Element Models in Modular Design

A modular design frame based on the static and dynamic analyses of structures by the finite element method (FEM) was put forward. To overcome the difficulty in data exchange between a CAD model and an FE model in a modular design system, three approaches,i.e.simple translation approach, standard parts library approach and central database approach, were proposed for different applications. The concrete measure of data transmission using the central database approach was discussed particularly.
