【摘要】 对不规则区域适应能力强、边界拟合程度高的铺砌法进行了改进。单元不再是逐层生成,而是逐个生成,大大简化了相交情况的判断和处理;在网格生成前对初始边界小内角节点进行先处理,增强了边界适应性;同时提出一种节点位置计算方法。用VC开发了相应的网格生成器,最后用算例进行了验证。更多还原

【Abstract】 Improve the paving method that is special applicable to irregular domain and get good element on the permanent boundary. The elements are generated one by one instead of row by row and the judgment and disposal of intersection are simplified tremendously. Those fixed points with small angle are disposed before generating mesh. The adaptability to boundary is enhanced strongly. The method is put forward to calculate the position of node. A mesh generator is designed based on VC. In the end, two examples are given to verify the algorithm.更多还原
