用于复杂流场数值模拟的重叠／嵌套网格方法

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。

An Overlapped/Embedded Grid Method For Numerical Simulation of Complex Flow Field

This paper introductions an overlapped/embedded grid method for numerical simulation of complex flow field. it is a type of multiple structured grid. it is to be used by the finite volume, finite difference solution algorithm with or without multigrid acceleration convergence. The thought is that divides the computational domain into less complex subdomains and allows the subdomain grids to be generated independently. the data transference of flow field between grid boundaries is accomplished by a trilinear interpolation procedure, solution algorithm is modified to exclude the hole cells from the flow result on the each subdomain grid.
