摘要
本文在单一矩形变换域贴体坐标网格生成方法的基础上,提出了结构块域贴体坐标网格数字生成方法,很好地解决了复杂几何形状,以及复杂拓扑结构的物理域变换问题,也为计算流体力学实施并行算法提供基础.
Based on the numerical grid generation of the body-fitted coordinate system on the single rectangular domain, the method of numerical grid generation of body-fitted coordinate system on structured block domains is presented in this paper. It can well solve the problem of the transformation of complex geometric physic domain or complex topological mesh into regular computational domain, thus making it possible for parallel algorithm to be used in computational fluid dynamics.
