In recent numerical simulations, it is very important to generate grids easily, as analysis objects become complex, and to use computer resources efficiently, which are limited. In this thesis, the kinds of grid, which have great effect on analysis accuracy and efficiency, are paid attention to. In the case of a two-dimensional problem, we usually use triangular or quadrilateral grid. The former, which has the advantage of freedom, can apply to complex objects better than the latter. The latter can analyze more efficiently than the former. So I used hybrid grid to take the advantage of both of freedom and efficiency. And I tried to analyze more efficiently, using HGA method that is AGR method, which obtains higher resolutions by collecting many grids only in the location where the change of the physical quantity is intense, based on Hybrid Grid.
