Development of adapter-codes for multiphysical simulations

At the University of Siegen (LSM group), we are currently developing different adapter codes to run partitioned simulations using preCICE as the coupling interface. In a first step, we coupled two solvers within the frameworks of deal. II and OpenFOAM (foam-extend) to simulate conjugate heat transfer problems. In a second project, a structural solver based on deal. II was coupled with an OpenFOAM solver, capable of handling dynamic mesh movement for FSI simulations. preCICE offers sophisticated post-processing methods, which considerably improved the convergence and stability of our implicitly coupled system. Additionally, the capability of peer-to-peer communication in case of parallel simulations was a reason to choose preCICE. From our point of view, preCICE proved to be a very promising and efficient coupling strategy supported by a committed community of users and a dedicated developer team. For the future, we would like to further improve our self-written adapters as well as test and integrate available adapters.
