The project will continue to study nonlinear wave-structure interaction for wave energy converters as well as offshore wind energy systems, mainly using the CFD software OpenFOAM. The overall aim is to study and improve the offshore survivability of these renewable energy systems. Dynamics and forces will be studied in different extreme waves conditions. The wave-structure interaction is highly nonlinear and must be resolved with CFD software, which are computationally demanding. Access to HPC clusters are a requirement for this research to take place. The existing project has thus far resulted in several journal and conference papers (SNIC has been acknowledged in all of them), as well as one PhD thesis (Linnea Sjökvist, 2017) and one licentiate thesis (Eirini Katsidoniotaki, 2021). The work forms the basis of Eirini Katsidoniotaki's PhD work.
