It is important to create adequate mesh according to the mesh rules in order to assure the quality of simulation results since simulation results may vary depending on the input FEM mesh. However, it is time consuming to create adequate FEM mesh according to the mesh rules. This paper describes how we automatically generate precise mesh following detailed mesh rules by recognizing various specific features from the shape of input 3D CAD models and its future development. To recognize specific features for the mesh rules, we used characteristics of each face of the input 3D CAD models. Which characteristics we check varies on the features. In addition to simple features, we also developed feature recognition algorithm to recognize composite surface features. We recognize them by combination of faces and their cross sectional shape as well as characteristics of each face. We also discuss the probable future development of the feature recognition.
