Numerical homogenization is a methodology for the computational solution of multiscale
partial differential equations. It aims at reducing complex large-scale problems to simplified …

Over the last decade, Computer Aided Engineering (CAE) tools have become essential in
the assessment and optimization of the acoustic characteristics of products and processes …

This chapter is devoted to the finite element analysis of Helmholtz problems on bounded
domains. Speaking of “Finite Element Analysis,” we elaborate on the computational analysis …

A new explicit time integration scheme is presented for the solution of wave propagation
problems. The method is designed to have small solution errors in the frequency range that …

In this paper, which is part II in a series of two, the investigation of the Galerkin finite element
solution to the Helmholtz equation is continued. While part I contained results on the h …

This article explores municipal acceptance of wind power in Sweden and draws conclusions
on the basis of semi-structured interviews with municipal decision-makers, together with …

When using the Galerkin FEM for solving the Helmholtz equation in two dimensions, the
error of the corresponding solution differs substantially from the error of the best …

Solving time-harmonic wave propagation problems by iterative methods is a difficult task,
and over the last two decades an important research effort has gone into developing …

For high wave numbers, the Helmholtz equation suffers the so‐called 'pollution effect'. This
effect is directly related to the dispersion. A method to measure the dispersion on any …

In this article we describe recent progress on the design, analysis and implementation of
hybrid numerical-asymptotic boundary integral methods for boundary value problems for the …
