This paper addresses the process of establishing a numerical model to accurately reproduce experimental results presented by Zhao et al. (2017) of three-dimensional (3D) gap resonance between two fixed ship-shaped boxes. The ship-shaped boxes were arranged in a side-by-side configuration to represent FLNG offloading and were subjected to NewWave-type transient wave groups. To develop the numerical model we employ the open-source Computational Fluid Dynamics (CFD) package OpenFOAM and systematically optimize mesh topology and size, domain size and boundary conditions. CFD is necessary for this problem to accurately reproduce the viscous losses and non-linear free surface effects that are observed in the experiments. The incident transient wave group used in the experiment is regenerated using various iterative schemes. The results show satisfactory agreements between the target and regenerated waves.
