Finite Elements for Helmholtz Scattering with Infinity as a Computational Boundary
Markus Wess, Anıl Zenginoğlu
Building on the null-infinity-layer construction, we develop an H1-conforming finite-element formulation of hyperboloidal compactification for the exterior Helmholtz equation. A ch…
A higher-order dual cell method for time-domain Maxwell equations
Lorenzo Codecasa, Bernard Kapidani, Joachim Schöberl +1
We present a higher-order extension of the dual cell method for the time-domain Maxwell equations in three spatial dimensions. The approach builds upon a variational reinterpretati…
A Krylov Eigenvalue Solver Based on Filtered Time Domain Solutions
Lothar Nannen, Markus Wess
This paper introduces a method for computing eigenvalues and eigenvectors of a generalized Hermitian, matrix eigenvalue problem. The work is focused on large scale eigenvalue probl…
Radial perfectly matched layers and infinite elements for the anisotropic wave equation
Martin Halla, Maryna Kachanovska, Markus Wess
We consider the scalar anisotropic wave equation. Recently a convergence analysis for radial perfectly matched layers (PML) in the frequency domain was reported and in the present…
Mass lumping the dual cell method to arbitrary polynomial degree for acoustic and electromagnetic waves
Markus Wess, Bernard Kapidani, Lorenzo Codecasa +1
We present a fundamental improvement of a high polynomial degree time domain cell method recently introduced by the last three authors. The published work introduced a method featu…
Complex scaled infinite elements for exterior Helmholtz problems
Lothar Nannen, Markus Wess
The technique of complex scaling for time harmonic wave type equations relies on a complex coordinate stretching to generate exponentially decaying solutions. In this work, we use…
