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…
