The structured meshes are widely utilized in the aircraft industry because of their efficiency in achieving accurate solutions, especially for viscous flows of complex configurations. However, they are usually generated by engineers through enormous and tedious interaction with the graphical user interface of mesh generation software. To address this issue, we implement one piece of interactive structured mesh generation software called NNW-GridStar. First, we present its design details, including the software architecture and data structure. Second, we demonstrate its implementation and emphasize on the accelerated techniques proposed in our software, which consist of automatic boundary-layer mesh generation, rapid block assembly, multiblock stretching, and O-type block stretching. Finally, we perform a deep comparison between the developed NNW-GridStar and another two pieces of well known commercial software, and then demonstrate the application of NNW-GridStar in the productional CFD simulations. Experimental results show that NNW-GridStar has an outstanding generation speed and can produce meshes with high quality.

结构化网格由于可以有效地获得准确的解决方案，特别是对于复杂配置的粘性流，因此在飞机行业得到了广泛的应用。但是，它们通常是由工程师通过与网格生成软件的图形用户界面进行的大量繁琐的交互操作生成的。为了解决这个问题，我们实现了一个称为NNW-GridStar的交互式结构化网格生成软件。首先，我们介绍其设计细节，包括软件体系结构和数据结构。其次，我们演示其实现并强调软件中提出的加速技术，包括自动边界层网格生成，快速块装配，多块拉伸和O型块拉伸。最后，我们在开发的NNW-GridStar和另外两个著名的商业软件之间进行了深入的比较，然后演示了NNW-GridStar在生产CFD模拟中的应用。实验结果表明，NNW-GridStar具有出色的生成速度，并且可以生成高质量的网格。
