| Abstract;We consider to solve the problem with finite difference method, in which physical values vary drastically toward the boundary. In this case, it is important to obtain the accurate solutions without increasing the number of grids in space. For a problem in such phenomena, so called as "stretching coordinate transformation" is used to concentrate the grids toward the boundary with the drastic increase or decrease of values. And we investigate the numerical error between approximate solution and exact solution of 2D-Laplace equation, and make clear the relationship between the error and the coordinate stretching parameter for the grid concentration.
