Optimal convergence for adaptive IGA boundary element methods for weakly-singular integral equations

Michael Feischl, Gregor Gantner, Alexander Haberl +1

In a recent work, we analyzed a weighted-residual error estimator for isogeometric boundary element methods in 2D and proposed an adaptive algorithm which steers the local mesh-ref…

Adaptive 2D IGA boundary element methods

Michael Feischl, Gregor Gantner, Alexander Haberl +1

We derive and discuss a posteriori error estimators for Galerkin and collocation IGA boundary element methods for weakly-singular integral equations of the first-kind in 2D. While…
