A HDG method with transmission variables for time-harmonic wave propagation problems with constant coefficients
Simone Pescuma, Gwénaël Gabard, Théophile Chaumont-Frelet +1
Iterative finite element solvers for time-harmonic wave problems are notoriously slow to converge, owing to fundamental properties of these problems. We present a variant of the hy…
A hybridizable discontinuous Galerkin method with transmission variables for time-harmonic acoustic problems in heterogeneous media
Simone Pescuma, Gwénaël Gabard, Théophile Chaumont-Frelet +1
We consider the finite element solution of time-harmonic wave propagation problems in heterogeneous media with hybridizable discontinuous Galerkin (HDG) methods. In the case of hom…
General method to retrieve all effective acoustic properties of fully-anisotropic fluid materials in three dimensional space
Arthur Terroir, Logan Schwan, Théo Cavalieri +3
Anisotropic fluid materials are of growing interest with the development of metamaterials and transformation acoustics. In the general three-dimensional case, such materials are ch…
Coupling of Finite-Element and Plane Waves Discontinuous Galerkin methods for time-harmonic problems
Mathieu Gaborit, Olivier Dazel, Peter Göransson +1
A coupling approach is presented to combine a wave-based method to the standard finite element method. This coupling methodology is presented here for the Helmholtz equation but it…
An integral formulation for wave propagation on weakly non-uniform potential flows
Simone Mancini, R. Jeremy Astley, Samuel Sinayoko +2
An integral formulation for acoustic radiation in moving flows is presented. It is based on a potential formulation for acoustic radiation on weakly non-uniform subsonic mean flows…
