Description
In the paper, authors are devoted to a study of the effect of the treatment of Neumann boundary conditions for one-dimensional advection-diffusion equation by the analysis method, and for two-dimensional Poisson equation by the numerical test method. The results show that the is first-order accurate in space O(h) scheme can be derived first-order accurate difference solution or second-order solution, and the O(h2) or O(h3) scheme is only derived second-order solution
