| 内容記述 | In this paper, a new grid generation scheme is proposed. In this scheme, several plausible geometrical conditions which should be satisfied by a grid are listed, and then, starting with an initial grid, modifications are made iteratively to the grid, until those conditions are satisfied. The present scheme is called a "geometrical method," in contrast to the existing algebraic and PDE approaches. The geometrical conditions listed in the 2-D case are; (1) Clustering in eta-directions (2) Orthogonalization near the solid wail (3) Smooth spacing distribution in the xi-direction (4) Smooth spacing distribution in the eta-direction (5) Smooth curvature distribution in thexi-direction (6) Smooth curvature distribution in theeta-direction (7) Minimum spacing in the xi-direction (8) Minimum spacing in theeta-direction The above conditions are realized by simple algorithms, and are combined with suitable weight factors. Several examples of 2-D geometries are shown, such as a NACA0012 wing section with angle of attack, a NACA0012 wing section with a spoiler and a flap, and a circular cylinder both for C-grid and O-grid. Extension to 3-D is straightforward and will soon be published. | |||||||||
