- W2600893086 abstract "In this paper, we compare the performance of the wave-based discontinuous Galerkin method against the polynomial high-order finite element method (FEM) for Helmholtz problems. Previous studies demonstrate that both methods lead to a control of the dispersion error associated with low-order FEM at high frequency. Common belief is that compared to polynomial methods, physics-based methods can provide a signifcant improvement in performance, at the expense of a deterioration of the conditioning. However, the results presented in this paper indicate that the diferences in accuracy, effciency and conditioning between the two approaches are more nuanced than generally assumed." @default.
