Abstract

Results submitted for the blind test challenge organised by CCP-WSI (2017) are presented in the article. Two numerical models are used to simulate physical experiments of wave groups interacting with a fixed FPSO-like structure. Specifically, the propagation of the waves is modelled with a Lagrangian 2D model, while the 3D wave-structure interaction is resolved in OpenFOAMR. Using the Lagrangian model to construct the numerical equivalent of the experimental basin and wavemaker allows the very accurate reproduction the incoming wave conditions. Lagrangian computations of surface elevation and kinematics are then used as boundary conditions of a much smaller Numerical Wave Tank (NWT) created in OpenFOAMR. Absorbing boundary conditions are implemented at the far end of the OpenFOAMRtank to suppress reflections. Results of wave run-up and pressure on the structure's surface are presented in the form requested for the blind tests.
