摘要：Accessing CAD geometry for mesh generation is one of the major technical issues related to moving simulation forward. This paper studies the automatic identification of features from CAD models based on STL files. The STL file generated with the well-known CAD software UG is used to transfer the surface geometrical data information. A new STL data file with topological connection is constructed for the calculation in the next. The geometric characters of the solid models are correctly identified by combining the edge-based method and the face-based method. It provides a foundation for precise matching of the element meshes to the boundaries of the solid model and improving the mesh quality. © (2012) Trans Tech Publications, Switzerland.
