- Abstract
In this paper, some fast algorithms using elliptical arc artificial boundary is designed to solve exterior anisotropic problems in concave angle domains. Some exact nonlocal boundary conditions are derived on the elliptical arc artificial boundary. Based on the above artificial boundary conditions, the Dirichlet-Neumann alternating method is presented. The convergence of this algorithm is examined. Finally, some numerical examples are given to show the effectiveness of our methods.
