Integration of finite element analysis (FEA) into design is important for complex product development. However, how to automatically and robustly generate the analysis model from the design model, and how to organize information needed by CAD and FEA for the efficient integration is still a big problem. In this study, analysis feature model (AFM) is proposed and developed as a central model for design and analysis. Five kinds of information are contained in AFM which are analysis-related information, geometric-related information, element-related information, boundary condition and coupling information between features. A systematic approach is elaborated to automatically generate the AFM from the design model which mainly contains four steps: automated recognition of analysis features, decomposition of the design model, reduction and combination into AFM. The analysis model can be easily obtained from the AFM. At last the proposed method is implemented and some examples are given.
