BEM解析支援エキスパートシステムの開発 : 第1報 オブジェクト指向知識表現を用いたBEMモデリング

The Boundary element method (BEM) is a useful engineering tool for structural analysis but there are various strategies to obtain the accurate solutions. We developed an expert system for two-dimensional elastostatic BEM analysis on the engineering work station (EWS). This system supports the input of shapes and boundary condition, modelling, BEM analysis, error estimation, adaptive meshing and post-processing. This paper describes the development of the user interface and the expert system for BEM modelling and meshing, which are developed by using object-oriented programming and representing of knowledge. It is found that the object-oriented representation of knowledge is very useful in the design of user interface and expert system in this study.
