Estimations for the values on interface lines are necessary in a domain decomposition method However, the accuracy of the estimations is of the first order for most of unconditionally stable domain decomposition schemes. In this paper. a second order of accuracy for the estimations on interface lines is presented With the new scheme, the optimal number of d
