    In the numerical studies, it is very important to accurately reflect the analyzing physical model, and usually the grid dependency tests are used to perform accurate numerical analysis by comparing the composition and size of the numerical grids. However, there is no obvious criterion for generating the composition and size of the grids in the grid dependency test. Meanwhile, the grid convergence index (GCI) method can numerically estimate the accuracy of the numerical analysis by estimation of discretization error through the grid generation. In addition, since the GCI calculation of a domain composed of the multi components can be affected by the grid configuration of each component, it is necessary to systematically analyze the correlation between the total grids and grids of each component. In this study, three-dimensional steady-state Reynolds-averaged Navier-Stokes analyses were performed with a turbulence model of shear stress transport to investigate the discretization error on the numerical grids of a Francis turbine model by the GCI method. The GCI calculations of total grids and grids of each component were conducted, and the enhanced effect of the total grids was confirmed by improving the component grids.
