摘要
六面体网格划分技术是三维有限元仿真软件处理的关键环节之一,等参映射法既可适应特殊的区域边界形状,又可控制所生成单元的形状和密度。对基于等参映射法的六面体网格划分原理进行了深入研究,并在此研究基础上对等参映射法的计算过程进行了细致的分析,利用VC++开发了该算法的相应程序,最后给出了2个等参映射法具体的应用实例,计算结果表明该程序的计算精度已经达到了工程要求。
The technique of hexahedral mesh generation is one of the most important processes in pre-process of software.Isoparametric mapping that is one way of transfinite interpolation,is not only suitable for the shape of boundary edge of special shape,but also the control of shape and density of mesh.It discusses the principle of generation of hexahedral mesh based on mapping technique and explains the function used in isoparametric mapping algorithm detailedly.It uses VC++ to implement the algorithm,shows examples of hexahedral mesh based on isoparametric mapping technique.The precision of hexahedral mesh computed by the programme can satisfy the requirement in engineering.
