Adaptive BEM with optimal convergence rates for the Helmholtz equation

Alex Bespalov, Timo Betcke, Alexander Haberl +1

We analyze an adaptive boundary element method for the weakly-singular and hypersingular integral equations for the 2D and 3D Helmholtz problem. The proposed adaptive algorithm is…

Adaptive BEM with inexact PCG solver yields almost optimal computational costs

Thomas Führer, Alexander Haberl, Dirk Praetorius +1

We consider the preconditioned conjugate gradient method (PCG) with optimal preconditioner in the frame of the boundary element method (BEM) for elliptic first-kind integral equati…
