The development of a fast multipole boundary element method for coupled acoustic and elastic problems

This thesis presents a dual fast multipole boundary element method (FMBEM) for modelling 3D acoustic coupled fluid-structure interaction problems in the frequency domain. Boundary integral representations are used to represent both the exterior fluid and interior elastic solid domains and the fast m...

Description
Summary:This thesis presents a dual fast multipole boundary element method (FMBEM) for modelling 3D acoustic coupled fluid-structure interaction problems in the frequency domain. Boundary integral representations are used to represent both the exterior fluid and interior elastic solid domains and the fast multipole method is employed to accelerate the calculations in both domains. The dual FMBEM yields a similar solution accuracy to the conventional models, while its solution times and memory requirements are substantially reduced.
