一种基于Delaunay背景图改进的网格变形方法
Improved mesh deformation method based on Delaunay background map
摘要
Abstract
This paper proposed an improved mesh deformation method based on Delaunay background map to increase the mesh quality after large deformation,which could be efficient to avoid failure due to bad mapping of the computational grid points to the Delaunay background mesh.Setting up much more far field boundary points than the original Delaunay deformation method make the number of mapping units in the background mesh increase,and the mapping accuracy for computational grid in the background mesh improve.Then,the quality of the grid after deformation became much better.Finally,it tested and verified the method separately through a deformation square grid case and 30P30N airfoil model case,the results indicate that the improved method can significantly increase the mesh quality after large deformation while ensuring the computational efficiency.Compared with the original method,the improved method can keep better ability of deformation and mesh quality.关键词
