Financial support by the Bayerische Forschungsstiftung in the Bavarian Consortium of High-Performance Scientific Computing (FORTWIHR) is gratefully acknowledged. The authors also want to thank Dr. J. Bellmann and Dr. C. Katz from SOFiSTiK AG, Munich, for technical support as well as some worthwhile discussions. The main part of the simulations were carried out on the Fujitsu VPP 700 machine of the Leibniz Computing Center, Munich. This support is also gratefully acknowledged.

N2 - In this paper a numerical approach of a time-dependent fluid-structure coupling for membrane and thin shell structures with large displacements is presented. The frame algorithm is partitioned, yet fully implicit because of a predictor-corrector scheme being applied to the structural displacements within each time step. In order to reach a high modularity, two powerful codes-one of them highly adapted to flow simulation and the other one to structural dynamics-run simultaneously and exchange fluid loads and displacements within each fluid-structure iteration. The finite volume based CFD code is able to compute three-dimensional, incompressible, turbulent flows. The structural simulations are performed using a finite element program including algorithms for geometrically and physically non-linear problems. In this paper the coupled algorithm will first be applied to some geometrically simple test cases to validate the interaction scheme. Then a real-life textile tent structure of glass-fibre synthetics with a complex shape is taken into account. This example was investigated under turbulent flow conditions at a high wind speed leading to a steady deformation state.
