Abstract

This paper presents a new technique in designing the finite difference domain decomposition algorithm for the heat-equation. The basic procedure is to define the finite difference schemes at the interface grid points with smaller time step \(\Delta\overline{t}=\Delta{t}/m\) (m is a positive integer) by the classical explicit scheme. The stability region of the algorithm is expanded m times comparing with the classical explicit scheme, and the prior error estimates for the numerical solutions are obtained for some algorithms when m=2 or m=3. Numerical experiments on stability and accuracy are also presented.
