摘要:
对于大型复杂的几何体，不可能仅通过一次算法自动剖分即得到高质量单元，剖分过程容易出现边界单元狭长、曲面内部单元尖锐等问题，由此，提出局部光顺优化算法。算法结合全局光顺方法以及局部网格拓扑结构优化方法的优点，避免了全局性优化算法计算量过大的缺陷，较传统优化算法，具有较好稳定性，通过实验验证，优化后的单元整体大小均匀、形状规整，在提高数值计算效率方面有较好表现。
Abstract:
For large and complicated geometry, it is not feasible to produce high quality mesh using automated algorithms at once. There are so many problems in meshing of faces, such as narrow elements on edges, sharp elements in face, and so on. In this paper, we present a local smoothing algorithm which combines the advantages of global smoothing method and local deterministic method. This algorithm avoids substantial consumption of computer resources and obtains more reliable results than the traditional algorithm. The implementation results show that the mesh elements will be well-distributed in size and homogeneous in shape after the refinement, and have excellent performance in numerical computation.
