| 摘 要： | 针对汽车、船舶等结构复杂部件的几何模型从CAD软件导入到CAE软件时经常产生孔、槽以及小曲面等"毛刺",在进行有限元划分时会产生网格缝隙而不能使用MSC Nastran计算的问题. 根据用MSC Patran对模型划分网格后网格缝隙相对较少,且每组缝隙仅含少量节点的情况,提出一种不修补模型而直接进行网格修补的方法,即使用邻接矩阵先对缝隙分类,然后使用不同的网格修补方法. |
| 关 键 词： | 三角网格 缝隙 邻接矩阵 网格优化 |

| Abstract: | As a result of the complexity of the FEM analysis models, the logical relationship of the model data is frequently lost in the transformation between CAD software and CAE software. The holes, slots and small curved surface caused by the failure of transformation will create triangle mesh gap in FEM analysis model, causing calculation divergence. Meshing model by MSC Patran shows that the number of gaps is comparatively small in relation to triangle and each gap group consists of only a few nodes. A new method using adjacency matrix to group gaps found in whole FEM analysis model is proposed. Algorithm for checking and optimizing the triangle quality is also provided. |
| Keywords: | triangle gap adjacency matrix triangle optimization |
