An extrapolation method for BEM. (English) Zbl 0673.65072
The boundary element method (BEM) is considered for a nonhomogeneous Dirichlet problem for the Laplace equation and the Richardson extrapolation formula for the Galerkin method is deduced. Numerical results of a test problem are given in support of the formula.
