In this seminar an overview will be given of the ERC AdG PortWings project and its achievements. The overview will first describe the initial goal and the context in which the project came to existence, and then will give attention to the various aspects of the results which have been achieved in the last years. This will include completely new methods to model and interconnect any multi-physical systems including the coupling of Navier-Stokes descriptions of fuids and non linear elasticity. Thanks to the new methodologies, novel numerical discretisation methods have been found which allow structure preserving integration of physical descriptions. This opens new possibilities on model reduction and control schemes able to use physically based models.
