Target Strength of Submarine with Outer Hull Using FEM-BEM
Application ID: 133521
This tutorial shows an approach to model the acoustic scattering off a submarine including the outer hull. The flooded volumes between the outer hull and the pressure hull are modeled with Pressure Acoustics, Frequency Domain (FEM) and the outside water domains with Pressure Acoustics, Boundary Elements (BEM). The properties of the outer hull are modeled using an approximate transfer impedance model of a thin plate. The impedance is added when coupling the FEM and the BEM domains using the Acoustic BEM-FEM Boundary multiphysics coupling.
