复杂区域四边形网格生成的基本模板法

A basic pattern moudule method is proposed to produce quadrilateral elements. The physical domains are mapped onto mathmatical domains which can be divided into basic pattern moudule on which the quadrilateral elements are generated. The method can control the mesh density effectively, and it is applicable in irregular domain and can generate joint elements.
