Abstract: A two dimentional adaptive numerical grids generation method and its particular realization is discussed. During Computational Fluid Dynamics, because the control values of adaptive grids-numerical solution is given in the descrite form, it needs to interpolate these values to get the continuous control functions. This paper discussed these interpolation techniques, and given some efficient adaptive grids. At last, a two dimentional fluid dynamics example was also given.

Key words: adaptive numerical grids, generation of numerical grids, computational fluid dynamics, two dimensional interpolation
