THE NONOVERLAPPING DDM BASED ON NATURAL BOUNDARY REDUCTION FOR 2-D EXTERIOR HELMHOLTZ PROBLEM
二维Helmholtz方程外问题基于自然边界归化的非重叠型区域分解算法

In this paper, based on natural boundary reduction suggested by Feng and Yu, an nonoverlapping domain decomposition method with its discretization is presented for the exterior problem of 2-D Helmholtz equation. The convergence of the D-N alternating algorithm and its discretization are studied. Some numerical results are given.
