| 摘 要： | 提出了一种全四边形网格生成算法．该算法先离散区域的边界，然后从边界开始向内部生成网格，根据边界上相邻节点内角的特征采用不同的生成策略．实现时进一步采用局部处理的方法，效率较高．由于只考虑区域的局部特征，网格质量较好，通用性较强．最后给出了网格生成的实例．

| Abstract: | An automatic method for generating all quadrangular mesh is proposed. The boundaries of a region are discretized, and then the meshes are generated inward from the boundaries. Different generation strategies are adopted according to the features of the interior angles of adjacent nodes on the boundary, and local processing method is used for further implementation with higher efficiency. Because it is only concerned with local features in a region, the meshes generated are of better quality. An example is given at last. |
