This paper describes an automated generation method of a hexahedral mesh named Intelligent Local Approach (ILA). Here elements are generated sequentially, by taking account of both local information on geometrical constraints and user's demand on quality of elements. Topological connectivity is first determined based on a heuristic category-based method. Then a fuzzy knowledge processing technique is utilized to determine optimum positions of nodes, considering various complicated geometrical constraints for high quality hexahedral elements. The determination of hexahedral connectivity and nodes positions is important technique to overcome difficulty in generating a hexahedral mesh of an arbitrary shape. Fundamental performances of the ILA are demonstrated in detail through generating several hexahedral meshes.
