摘要:本文针对剪力墙结构提出了一种新的自由网格划分方案，使得剪力墙结构的有限元离散模型更加合理，从而提高有限元分析的精确性和可靠性。该方案以铺砌法自由网格算法为核心并联合几何拆分法和映射网格法，兼顾自由网格的通用性和映射网格的高效性，既满足各种复杂结构模型的要求，又提高网格划分的质量，并同时确保网格划分的速度，从而节省结构分析的总时间。
Abstract: This paper presents an new unstructured mesh generation method which is specially adapted to shear wall structures, making the discretization of the continuity more reasonable and enhancing the accuracy and reliability of the finite element analysis. Based on paving method and combining the mapping method and decomposition method, the meshing method developed in this paper can increase the quality and efficiency of automated mesh generation and meet the requirement of complicated structural analysis.
