FSI coupling with multibody dynamics

When fluid-structure interaction involves slender or flat structures, it is interesting to apply reduced dimensionality models (e.g. shells, or beams) to perform such computations. We coupled MBDyn (an open source multibody dynamics software developed at Politecnico of Milan) to preCICE within a master thesis project, exploiting the C++ interface provided by MBDyn. We validated the set-up in the incompressible regime coupling MBDyn and OpenFOAM and comparing our results with the well-known Turek & Hron benchmarks, which proved to be challenging because of added mass instability issues. Some preliminary results can be found in the thesis , while an extensive validation has been described in a conference paper . Learn more
