摘要
首先,本文说明了研制网格生成软件对于促进计算流体力学研究和应用的重要意义。其次,本文论述了数值网格生成的基本概念和基本步骤,提出了网格生成软件GRGES的设计思想,简单介绍了GRGES的总体结构和五种网格生成方法。最后给出了三个网格生成算例,它们均可用于计算实际流场。
First, this paper shows that grid generation software has important significance for the research and application of computational fluid dynamics. Then, it states the fundamental concepts and steps of numerical grid generation. At the same time, the design ideas of grid generation software GRGES are also stated. The global framework of GRGES and five methods of grid generation are described briefly. Finally, three examples of grid generation are presented, they may all be used to compute actual flow fields around a body.
