An adaptive finite element solver for fluid–structure interaction problems

Abstract

Fluid–structure interaction (FSI) occurs when a fluid interacts with a solid structure, exerting a traction force that causes deformation of the structure and, thus, alters the flow of the fluid itself. The FSI problem is a fully coupled multiphysics problem, whether the problem is solved in a partitioned manner or by a monolithic approach. In many cases we are only interested in one physical output quantity of the fully coupled system, e.g., the displacement of the structure. In order to compute ths particular physical output of interest with a high level of accuracy, a goal oriented adaptive finite element method can be used.
