Abstract: The article characterises the progress in numerical simulation of fluid-solid-interaction seen from an ANSYS^® (commercial software package from ANSYS, Inc., Canonsburg, USA) perspective within the last ten years. Starting with a discussion of the physical nature of the interaction (negligible effects) a wide range of solution strategies from load mapping, via the staggered solution scheme for general load vector field couplings to immersed solid capabilities and acoustic FSI are presented. The implementation of important features for solving like the general grid interface, relaxation, morphing and re-meshing is covered as well as the role of the whole FSI-simulation as part of product life cycle management (PLM) workflow. Seen with the eyes of a software user important convenience features are touched as well to underline that such simulations made their step into every day engineer's practice.
