Coupling techniques in boundary-combined methods for solving elliptic problems with singularities
Engineering Analysis with Boundary Elements(1993)
Abstract
Three coupling strategies in matching the Ritz-Galerkin method and the finite element method are introduced for general elliptic equations, and useful numerical techniques are provided. Numerical experiments have been carried out for solving the typical, singular Motz problem, which shows that optimal convergence rates of numerical solutions can be achieved by using the combined methods and techniques provided in this paper.
