摘要
网格是开展大多数数值模拟计算的必要条件。面向高性能数值模拟应用,几何结构日趋复杂,局部特征日趋精细,网格规模将达到十亿规模以上,这就要求网格生成既要高效处理复杂模型,又要自适应刻画局部特征,更要考虑大规模网格向解算器的低开销传输,因此研制并行网格生成软件对推动高性能数值模拟应用具有重要价值。首先从算法研究、软件产品化两个层次论述相关领域的国内外情况,接着介绍了自主可控软件SuperMesh的架构设计和关键技术进展,最后探讨了并行网格生成技术的未来发展方向。
Mesh is indispensable for many numerical simulations. Nowadays, geometries processed in highperformance numerical simulations become more and more complicated. Meanwhile, an increasingly higher requirement of fine-grained local features makes a one-billion mesh, which was unimaginable before, quite common. Consequently, mesh generation methods are supposed to be able to handle complicated geometries efficiently and capture fine local features adaptively at the same time. In addition, the transmission bottleneck when passing large-scale meshes to the solver needs to be avoided. Therefore, the development of more efficient parallel mesh generation softwares is of great practical value for promoting high-performance numerical simulations. Firstly, the latest research progress at home and abroad are summarized in terms of algorithms and software products. Secondly, the architecture design and key technologies of the in-house designed software SuperMesh are introduced. Finally, the development trend of parallel mesh generation technology is discussed.
