The Improvement of Advancing Front Method for the Generation of Unstructured Grid

ZHAO Bin,WANG Xu(The Engineering Institute of the Air Force Engineering University, Xi'an 710038, China)  
According to the analysis of the advancing front method for the generation of unstructured grid, this paper put forward an efficient algorithm by optimization, adopt to structured background grid replacing unstructured background grid, and the scale of grid is gained through making use of control volume finite element to solve Possion function with the Dirchlet boundary condition. This paper introduces the Laplacian operator and the technology of exchanging of opposite angle to improve the quality of grid. At the time of programming, the dynamic data structure of link list and the new data type are used to speed up the process of grid generation. 
