介绍了一类用于复杂流场数值模拟的重叠／嵌套网格方法。它是一类多块结构化网格，可用于有或无多重网格加速收敛技术的有限体积、有限差分等计算。其基本思想是把复杂流场的计算区域化分成相对简单的子区域，每个子区域上的网格可以独立生成；网格界面之间的流场信息交换通过三线性插值来实现，通过修改流场解算方法来排除洞中的点。 A class of overlapping / nested grid methods for numerical simulation of complex flow fields is introduced. It is a class of structured grids that can be used for finite volume, finite difference, etc. calculations of accelerated convergence techniques with and without multiple meshes. The basic idea is that the computational regionalization of complex flow field is divided into relatively simple subregions, and the grids in each subregion can be generated independently. The flow field information exchange between grid interfaces is realized by tri-linear interpolation. By modifying the flow Field solver method to exclude holes in the hole.
