摘要
以Helmholtz方程为例,基于坐标变换及自然边界归化理论,提出了一种带圆型人工边界的重叠型区域分解算法.构造其算法并讨论其相应的收敛性,证明了算法是几何收敛的.
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.
