In this paper, we present a method for the analysis of the motion behaviour and also the structural response–stresses and deformations–of a floating wind turbine. A partitioned approach is chosen to solve the fluid-structure interaction problem. Therefore, our C++ library comana, developed to couple various solvers, is enhanced to couple the fluid solver pan MARE and the structural solver ANSYS. Initially, a simple elastic finite element model is used in the coupled analysis. This finite element model is described, and some results of the coupled simulation are presented. In order to use a more detailed finite element model without drastically increasing the computation time, superelements can be employed. This procedure is described and applied to an example, a floating buoy in waves, to demonstrate its applicability in fluid-structure interaction simulations.
