Comparison of $\mathcal{H}$-matrix- and FMM-based 3D-ACA for a time-domain boundary element method

Martin Schanz, Vibudha Lakshmi Keshava, Herbert de Gersem

The homogeneous wave equation is solved by a time-domain boundary element method (BEM) using low-order shape functions for spatial, and the generalised convolution quadrature metho…
