REEF3D::FNPF – A Flexible Fully Nonlinear Potential Flow Solver
Bihs, Hans; Wang, Weizhi; Pakozdi, Csaba; Kamath, Arun (Peer reviewed; Journal article, 2020)In situations where the calculation of ocean wave propagation and impact on structures are required, fast numerical solvers are desired in order to find relevant wave events. Computational fluid dynamics (CFD)-based numerical ... -
Representation of 3-h Offshore Short-Crested Wave Field in the Fully Nonlinear Potential Flow Model REEF3D::FNPF
Wang, Weizhi; Pakozdi, Csaba; Kamath, Arun; Bihs, Hans (Peer reviewed; Journal article, 2022)Stochastic wave properties are crucial for the design of offshore structures. Short-crested seas are commonly seen at the sites of offshore structures, especially during storm events. A long time duration is required in ... -
Representation of Breaking Wave Kinematics in the Fully Nonlinear Potential Flow Model REEF3D::FNPF
Pakozdi, Csaba; Kamath, Arun; Wang, Weizhi; Bihs, Hans (Chapter, 2020)Robust simulations over three-hours are essential to represent a stationary sea state and derive wave statistics and structural response of marine structures in a reliable manner. This means that the numerical model used ... -
Simulation of breaking focused waves over a slope with a CFD based numerical wave tank
Alagan Chella, Mayilvahanan; Bihs, Hans; Pakozdi, Csaba; Myrhaug, Dag; Arntsen, Øivind Asgeir (Chapter, 2017)Extreme wave conditions are always identified with large-amplitude breaking waves in shallow waters. Focused waves can often be used to describe extreme waves which evolve during the nonlinear wave-wave interaction, occurring ... -
Validation of Numerical Wave Tank Simulations Using REEF3D With JONSWAP Spectra in Intermediate Water Depth
Pakozdi, Csaba; Fouques, Sebastien; Thys, Maxime; Kamath, Arun Mulky; Wang, Weizhi; Hoseini Dadmarzi, Fatemeh; Bachynski, Erin Elizabeth; Bihs, Hans Sebastian (;Paper No: OMAE2020-18298, V001T01A012, Chapter, 2020)As offshore wind turbines increase in size and output, the support structures are also growing. More sophisticated assessment of the hydrodynamic loads is needed, particularly for the ultimate limit state design. For ...
