Abstract A high-order characteristic-difference method for the nonlinear convection-dominated diffusion problem is considered. The method is of order two for the diffusion term and of order m(≥3) for the convection term. The error estimates of the scheme are given. Numerical computations for the model problem of [4] are presented. The numerical results show that the method is better than the Godunov-mixed method of [4].
