A p‐adaptive algorithm for the BEM with the hypersingular operator on the plane screen

Abstract: SUMMARYWe propose a p-adaptive algorithm for the Galerkin method solving the hypersingular integral operator of the Laplacian on the plane screen. The error indicators=estimators are based on projections of the actual error onto local subspaces. These subspaces are deÿned by decompositions of specially designed enriched ansatz spaces. Our algorithm uses di erent strategies for the reÿnement and the stopping criterion. The error estimator that stops the algorithm is based on an overlapping decomposition of an a… Show more

“…Numerical results for this algorithm are presented in [6] and [7] for a hypersingular integral equation on a surface piece modeling a scalar screen problem in R 3 ; the resulting hp-refinements give suitably refined meshes together with appropriate distributions of polynomial degrees. The corresponding implementation for the eddy current problem above can be performed with the program package maiprogs [13]; for the pure h-version corresponding numerical experiments are given in [20].…”
