摘要
基于等参映射，提出了生成全四边形网格的基本模板法，该方法将物理空间的简单区域映射至数学面上划分，利用数学面上的基本模板生成单元，能够非常有效地实现网格的疏密过渡，能处理复杂的介质区域。
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.
