| Abstract: | A non-overlapping domain decomposition algorithm which is based on the elliptic artifial boundary for solving the two-dimensional harmonic problems over unbounded domain is offered and iterative convengence of its discreted form is discussed. Theoretical analysis as well as numerical results show that this method is very efficient for exterior two-dimentional harmonic problems in elongted domains. |
