This paper describes the automatic mesh generation system for 2D axisymmetric and 3D shell structures based on the fuzzy knowledge processing. In this system, an analysis model, i.e. a geometric model, is first defined using a conventional method for 2D structures and a commercial CAD system, Auto-CAD, for 3D shell structures. Nodes are then generated based on the fuzzy knowledge processing technique, well controlling the node density distribution over the whole analysis domain. Triangular elements are generated using the Delaunay triangulation technique. The triangular elements are converted to quadrilateral elements. The fundamental performances of the system are demonstrated through its application to typical components of a pressure vessel.
