Are you looking for an efficient solution for calculating the sound emission of large structures such as ships in the high-frequency range? Classical numerical methods such as the finite element method (FEM) or the boundary element method (BEM) quickly reach their limits, as the fine mesh resolution for higher frequencies leads to problem sizes that exceed the given computing resources.
This document describes the application of the energy-based finite element method (EFEM) to a ship. The EFEM is based on the equalization of input, output and dissipated powers via a special control element and is applicable to fluid and structural problems.
Learn more about the theoretical aspects of EFEM
Understand the coupling of fluid and structural problems based on radiation efficiency
Discover the influence of the coupling parameters on the resulting system of equations
This document provides valuable insights and defines a lower frequency limit for the application of EFEM to vibrating ship structures.
