摘要：
In this paper, we present an upwind finite volume method to solve the convection-diffusion equations with Dirichlet boundary on rectangular mesh. By utilizing the technique of element-by-element analysis, the stability of the method has been proved and the H-1-norm error estimate is presented. Furthermore, we provide the proofs of the maximum principle and L-infinity-norm error estimate. Finally, some numerical experiments are provided to confirm our theoretical results.
