Abstract: | ![]() In this work, we study the convergence behavior of a recently developed space‐time conservation element and solution element method for solving conservation laws. In particular, we apply the method to a one‐dimensional time‐dependent convection‐diffusion equation possibly with high Peclet number. We prove that the scheme converges and we obtain an error bound. This method performs well even for strong convection dominance over diffusion with good long‐time accuracy. Numerical simulations are performed to verify the results. © 2001 John Wiley & Sons, Inc.
