摘要: 在继承已有研究成果的基础上,发展一种任意不规则区域全自动四边形网格划分方法。四边形网格生成算法思想来源于AFGT法,即单元与节点同时生成。并利用FORTRAN语言编制了通用计算程序,只需输入少量边界信息,即可实现网格的自动划分,同时配以图形自动绘制和屏幕显示。应用示例表明,该方法网格生成速度快,网格质量高。

Abstract: A new mesh auto -generation algorithm of arbitrary quadrilateral is presented. This algorithm is based on AFGT(advanced front generation technique) method which can generate elements and nodes simultaneously. Computing programme has been developed in FORTRAN language which can implement auto-division of meshes easily with less inputinformation. An illustration shows that this algorithm can generate meshes in short time with higher quality. 
