| Abstract | MAG3D (Multi-block Adaptive Grid, 3D) is a three-dimensional solution-adaptive grid generation code which redistributes grid points to improve the accuracy of a flow solution without increasing the number of grid points. The code is applicable to structured grids with a multi-block topology. It is independent of the original grid generator and the flow solver. The code uses the coordinates of an initial grid and the flow solution on that grid to produce the coordinates of a solution-adapted grid and the flow solution interpolated onto the new grid. MAG3D uses a numerical mapping and potential theory to modify the grid distribution based on properties of the flow solution on the initial grid. In this paper, the adaptation technique is discussed, and the capability of MAG3D is demonstrated with several internal flow examples. Advantages of using solution-adaptive grids are also shown by comparing flow solutions on adapted grids with those on initial grids. |
