An Circular Artificial Boundary Overlapping Domain Decomposition Algorithm Based on Coordinates Changing and Natural Boundary Reduction Theory

ZUO Wen-qi,WANG Shou-cheng(Hefei University of Technology,School of Mathematics,Hefei 23009,China)  
An circular artificial boundary overlapping domain decomposition algorithm was proposed based on the coordinates changing and natural boundary reduction theory for solving the Helmholtz equation.The algorithm was constructed and the convergence was discussed.It is proved that the convergence rate of the algorithm is geometrical.
