• A comparison of different wave modelling techniques in an open-source hydrodynamic framework 

      Wang, Weizhi; Kamath, Arun; Pakozdi, Csaba; Bihs, Hans (Journal article; Peer reviewed, 2020-07-16)
      Modern design for marine and coastal activities places increasing focus on numerical simulations. Several numerical wave models have been developed in the past few decades with various techniques and assumptions. Those ...
    • Complex geometry handling for a cartesian grid based solver 

      Bihs, Hans; Kamath, Arun; Alagan Chella, Mayilvahanan; Pakozdi, Csaba (Chapter, 2017)
      Complex geometries can be a challenge for computational fluid dynamics (CFD) solvers that use a Cartesian mesh. In the current paper, an algorithm is described with which complex geometry features can be incorporated in a ...
    • Efficient Wave Modeling Using Non-Hydrostatic Pressure Distribution and Free Surface Tracking on Fixed Grids 

      Bihs, Hans; Kamath, Arun; Aggarwal, Ankit; Pakozdi, Csaba (ASME 2018 37th International Conference on Ocean, Offshore and Arctic Engineering;Volume 2: CFD and FSI;OMAE2018-78158, Chapter, 2018-06-25)
      For the estimation of wave loads on offshore structures, relevant extreme wave events need to be identified. In order to achieve this, long term wave simulations of relatively large scales need to be performed. Computational ...
    • Influence of the upstream cylinder and wave breaking point on the breaking wave forces on the downstream cylinder 

      Kamath, Arun; Alagan Chella, Mayilvahanan; Bihs, Hans; Arntsen, Øivind A. (SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)
      The interaction of breaking waves with marine structures involves complex free surface deformation and instantaneous loading on the structural members. A typical offshore platform or a coastal structure consists of ...
    • Investigation of Higher-Harmonic Wave Forces and Ringing Using CFD Simulations 

      Kamath, Arun; Bihs, Hans; Pakozdi, Csaba (ASME 2018 37th International Conference on Ocean, Offshore and Arctic Engineering;Volume 7B: Ocean Engineering;OMAE2018-77925, Chapter, 2018-06-25)
      Typical offshore structures are designed as tension-leg platforms or gravity based structures with cylindrical substructures. The interaction of waves with the vertical cylinders in high sea states can result in a resonant ...
