| 摘 要： | 提出一种新的曲面有限元网格生成方法，将曲面边界离散相邻节点连接构造线段序列，并从序列中的线段出发，以线段的空间位置为依据，构造圆，再利用该圆在曲面上布点筛选求取网格节点，生成单元，使节点一单元一线段交替生成，该方法实现了曲面均匀网格的自动生成，网格质量良好，适用于不同形式的曲面，具有很大程度的通用性，有利于解决有限元分析建模的瓶颈之一——曲面网格自动生成问题。

| Abstract: | A new method for curved surface finite element mesh generation was put forward,in which the surface boundary is discretized and the adjacent nodes are linked to construct a segment list. By the segments in the list and according to its space position,a circle is constructed,which is used to position nodes on the curved surface,thus generating new mesh nodes and a new ele ment. So the node,element and segment are alternately generated. By this method,the curved surface uniform meshes with high quality can automatically be generated. This method is suited to various curved surfaces. It is also common to solving the key problem of automatic curved surface mesh generation in finite element modeling. |
