Abstract

This work discusses adaptive iterative coupling strategies for the frequency domain analysis of interacting acoustic-elastodynamic models. The method of fundamental solutions (MFS) is used to analyze acoustic fluids, whereas the finite element method (FEM) is employed to discretize elastodynamic solids. Flexible and optimized iterative MFS-FEM coupling procedures are considered, allowing independent discretizations to be adopted for each subdomain. In this context, it is easy to implement adaptive refinements and enable enhanced analyses. Two adaptive coupling approaches are discussed, based on multiple and single iterative algorithms. Numerical results are presented to illustrate the performance of the proposed techniques.
