| 中文摘要: |
| 本文基于波前法提出了一种对任意平面区域生成三角形网格自动生成算法。算法具有区域适应性强，边界网格质量高，自动化程度高的优点。算法还包括了网格的拓扑优化，光滑及加密处理。此外，初边值条件的自动给定大大减少了数值计算中数据输入和避免了边界搜索计算。大量算例显示了算法的可靠性和适用性。 |
| 英文摘要: |
| HT5SS]Based on the advancing front method, an automated triangular mesh generation algorithm for arbitrarily shaped planar regions is presented in this paper. The proposed algorithm has the advantages of adaptation to complicate boundaries, high quality boundary mesh and full automation. Approaches such as topological refinement and smoothing are incorporated. Initial and boundary conditions can also be specified after triangulation, which leads to the greatly reduced data input as well as the avoidance of calculation due to boundary searching. Examples are included to demonstrate the capabilities of the algorithm. |
