摘要

This paper describes a new mesh generation algorithm, namely Intelligent Local Approach, which controls well size and aspect ratio of quadrilateral and hexahedral element simultaneously. Here we define the following three fields, i. e. a distribution of element size, that of aspect ratio and that of priority of element creation. The ILA also ensures mesh quality. In ILA, elements are created sequentially considering local information on geometrical constraints and user's demand on quality of the element to be created. To efficiently deal with various complicated geometrical constraints in a local region, a fuzzy knowledge processing technique is effectively utilized. Fundamental perfor- mances of the ILA are examined in detail through generating several quadrilateral meshes.
