Finite-element modeling in ocean acoustics: Where are we heading?

Abstract: This paper summarizes 10 years of NURC experience with the application of a state-ofthe-art FE code [Zampolli et al., JASA 122, 1472-85 (2007] to propagation and scattering problems in ocean acoustics. We show benchmark results for low-frequency propagation in a range-dependent waveguide with an elastic bottom, and object scattering results for spheres and cylinders placed near the seafloor. Despite the computational burden associated with the FE method, its generality in treating propagation in layered fluid-… Show more

“…In the case of rough, layered sediments, numerical methods such as the finite element method (FEM) provide an attractive option. The FEM discretization of the governing acoustic wave equations in underwater domains enables accurate modeling of the seafloor environment [51,52,53,54,55,56,57,58]. Not limited by constraints on the degree of surface roughness or range dependence, FEM offers flexibility and can incorporate physics generated from realistic scenarios.…”
