Numerical Efficiency of Different Partitioned Methods for Fluid‐Structure Interaction

The numerical simulation of coupled problems is one of the great challenges in scientific computing. In this paper, we consider partitioned methods for unsteady fluid-structure interaction, where different codes are used for the different physical domains. There are various procedures how to couple the fluid and structure part: the coupling conditions and the moving domain can be treated in a fully explicit or implicit or in a mixed explicit/implicit manner. Depending on the different coupling procedures, the numerical efficiency of the staggered partitioned methods is investigated.
