摘　　要：通过对比风工程数值模拟中可供选择的各种网格技术,深入分析了几种网格各自的特点。结构网格与非结构网格的优缺点基本是对立互补的,混合网格技术代表了当前和未来网格技术的主要发展趋势。自适应笛卡尔网格自动化程度高,对于各向同性流动问题极具优势。由于目前从事计算风工程的专业人员网格生成能力较差,自适应笛卡尔网格特别适合于风工程的低速复杂湍流问题的模拟。Several grid generation technologies are compared based on computational wind engineering. The advantages and disadvantages of structured grids and unstructured grids are opposite and mutually complementary, so mixed grids represent the current and future major development trend of grid generation. Adaptive Cartesian grids can be generated automatically, and show a greal advantage for isotropic flow simulation. Adaptive Cartesian grids are particularly suitable for low speed complex turbulence flow simulation on wind engineering, for most professionals currently have a poor capaeity for grid generation.
