The paper describes the techniques used for fluid-structure interaction analyses in the project IMENS+ (DLR, TU Braunschweig), with emphasis on the software concept used. The project’s aim is the development of an integrated environment for the multidisciplinary design of hot structures, targeting hypersonic aerospace applications. Although fluid-structure interaction problems have been the target of research for many years now, there is still a lack of adequate simulation environments for industrial use with regard to user-friendliness and flexibility. The activities in the project IMENS+ aim at developing an integrated environment for coupled simulations, having as main requirements: ability to handle complex physical models, performance, ease of use and flexibility. These requirements led to a modular software concept using existing solvers for the individual disciplines (fluid and structural dynamics). These solvers are optimized for their disciplines (use in general different solution schemes), are very robust and can handle complex physical models.
