Abstract: In this paper, we build the asymptotic expansion of solution of Du Fort-Frankel scheme for diffusion problem and then use extrapolation. The accruacy of the extrapolation solution may achieve O(τ2+h4) and the limitation of consistency is improved greatly.
Key words: the asymptotic expansion of the solution for Du Fort-Frankel scheme, extrapolation, reducing the computational work
