Are you looking for an efficient solution to calculate the acoustic emission of large-scale structures such as ships in the high-frequency range? With classical numerical methods such as the finite element method (FEM) or the boundary element method (BEM), you quickly reach limits, since the fine mesh resolution for higher frequencies leads to problem sizes that exceed given computational resources.
This paper presents the application of the energy-based finite element method (EFEM) to a ship. The EFEM is based on the balancing of input, output and dissipated powers via a special control element and is applicable to fluid and structural problems.
