Abstract

A fixed-point fluid-structure interaction (FSI) solver with dynamic relaxation is revisited. New developments and insights gained in recent years motivated us to present an FSI solver with simplicity and robustness in a wide range of applications. Particular emphasis is placed on the calculation of the relaxation parameter by both Aitken's Δ2 method and the method of steepest descent. These methods have shown to be crucial ingredients for efficient FSI simulations.
