| Abstract: | This paper presents a simple and general method for generating adaptive computational grids. The procedure can be implemented with grid optimization method of reference 1], and adaptive grids produced with high quality smoothness and orthogonality. It is pointed out that the selection of grid cell weighting function W and the distribution of grid points on the boundary may have significant influence on the grid quality. As an application example, the 2-D inviscid transonic cascade flow is solved by using adaptive grids. The result shows that the accuracy of calculation can be improved when the adaptive grids are employed |
