There is an increasing interest to refine the numerical simulation of the unsteady aerodynamics, the wake development and its interaction with atmospheric boundary layer and gust to finally predict the transient loads and extreme loads acting on the blades of turbines in the first row and the ones behind. For this purpose a CFD based process chain is being developed and applied at the institute of aerodynamics and gasdynamics (IAG), University of Stuttgart. The process chain consists of a grid generator with scripting capability for automated meshing, the block structured flow solver FLOWER, which is provided by the German Aerospace Center (DLR) and optional of a multibody simulation code with a grid morpher for aeroelastic simulations. The aeroelastic coupling scheme is described in  along with application examples.
