摘要: In this paper, the numerical approximation of unsteady convection-diffusion-reaction equations with finite difference method on a special grid is studied in convection or reaction-dominated regime. We extend 19] which was designed for multidimensional steady to problems. investigate two possible different ways combining discretization time and space (where sequence discretizations interchanged). Discretization performed by using Crank-Nicolson Backward-Euler schemes, while we consider 19]. Numerical tests are presented show good performance method.
