The boundary element method (BEM) in the context of acoustics or Helmholtz problems is
reviewed in this paper. The basis of the BEM is initially developed for Laplace's equation …

State-of-the-art finite-element methods for time-harmonic acoustics governed by the
Helmholtz equation are reviewed. Four major current challenges in the field are specifically …

We present a collection of 52 nonlinear eigenvalue problems in the form of a MATLAB
toolbox. The collection contains problems from models of real-life applications as well as …

Low noise constructions receive more and more attention in highly industrialized countries.
Consequently, decrease of noise radiation challenges a growing community of engineers …

The Element-Free Galerkin Method (EFGM), a particular case of the meshless methods, is
examined in its application to acoustic wave propagation addressed by the Helmholtz …

Summary The Dirichlet-to-Neumann (DtN) Finite Element Method is a general technique for
the solution of problems in unbounded domains, which arise in many fields of application. Its …

A subgrid scale method has been developed for the advection–diffusion-reaction equation
with a simple intrinsic time-scale parameter. The proposed formulation combines very good …

Advanced Computational Vibroacoustics presents an advanced computational method for
the prediction of sound and structural vibrations, in low-and medium-frequency ranges …

A new approach called the “variational theory of complex rays”(VTCR) is developed for
calculating the vibrations of weakly damped elastic structures in the medium‐frequency …

The first step when solving an infinite-dimensional eigenvalue problem is often to discretize
it. We show that one must be extremely careful when discretizing nonlinear eigenvalue …
