\section{Numerical Results}
\label{sec:results}

In this section, several numerical results for different problems and geometries in two and three dimensions are presented. 
\revadd{The evaluation of matrix entries is performed by numerical integration and an adaptive scheme (see~\protect\ref{sec:integration}), which ensures a user-defined quadrature error~\protect$\err_Q$.}{Introducing the symbol for the integration error}
The superiority of the isogeometric BEM in terms of geometry error compared to standard and higher order Lagrangian boundary elements has already been shown in other publications such as \cite{Simpson2012a} or \cite{Simpson2014a}. Hence emphasis is given to the higher order convergence as well as to the saving of computational costs due to the presented subparametric formulation and the application of \hmatrices{}. 
The presented implementation utilises the \emph{HLib} library~\cite{hlib} for the representation of the \hmatrix{} format and matrix operations.
