摘要

结构网格具有边界层模拟准确、计算效率高等优势，在当前的计算流体力学（CFD）研究和工程应用中被大量采用。然而，复杂外形的结构网格生成非常耗时，通常需要在图形化软件上借助频繁的交互操作来实现，对CFD研究和应用产生了重要影响。针对此问题，提出了附面层推进、网格块自动补齐、网格分布快速调整、破损数模网格优化等网格生成加速技术。依托国家数值风洞工程，研发出一款通用型结构网格生成软件——网格之星（NNW-GridStar）。与主流商业软件Pointwise相比，网格之星的网格生成速度更快。经过大量复杂算例验证，网格之星满足工程应用要求。自软件发布以来，已有80余家科研院所下载使用，为实际工程任务提供了重要的支撑作用。

Abstract

With the advantages of accurate boundary-layer simulation and high computational efficiency

structured grid is widely used in the Computational Fluid Dynamics (CFD) research and engineering applications. However

the grid generation of complex model is very time-consuming

which usually requires frequent interactive operations in the graphic software. To solve this problem

we propose acceleration techniques in grid generation

such as boundary-layer generation

rapid block assembly

rapid adjustment of grid distribution and grid optimization of dirty model. Relying on National Numerical Windtunnel (NNW) project

we develop NNW-GridStar

a general structured grid generation software. This software supports the automatic generation of boundary-layer gird and has great advantages in the generation acceleration of volume grid

greatly improving the generation efficiency. Compared with Pointwise

NNW-GridStar generates grid faster and the quality of the generated grid is equivalent. A large number of complex cases show that NNW-GridStar meets the requirements of engineering applications. Since the release

this software has been downloaded and used by more than 80 scientific research institutes

greatly supporting the practical engineering tasks.
