Xavier Claeys, Francis Collino, Emile Parolin

摘要:

我们引入了一个新的区域分解策略的时间谐波麦克斯韦方程组的情况下,自动生成的子域分区可能存在的交叉点是有效的。算法的收敛性是有保证的,我们提出了一个完整的分析矩阵形式的方法。该方法涉及负责施加子域之间的耦合的传输矩阵。我们讨论了这样的矩阵的选择,他们的建设和这种选择的区域分解算法的收敛性的影响。数值结果和算法提供。

英文摘要:

We introduce a new domain decomposition strategy for time harmonic Maxwell's equations that is valid in the case of automatically generated subdomain partitions with possible presence of cross-points. The convergence of the algorithm is guaranteed and we present a complete analysis of the matrix form of the method. The method involves transmission matrices responsible for imposing coupling between subdomains. We discuss the choice of such matrices, their construction and the impact of this choice on the convergence of the domain decomposition algorithm. Numerical results and algorithms are provided.
