In this study the influence of grid effects on free surface deformations behind a ship-like moving vessel were investigated. To determine the influence of grid effects on the water wave propagation, various grid domains with different quality parameters were produced. Simulations were conducted for a moving pressure source and the free surface around the moving body captured. Then three-dimensional numerical results for different grids, in both the near and far field, were compared with experimental data over a range of speeds. The experimental data were obtained using tank tests on a pressure source model at the Australian Maritime College. Wave probes at different lateral distances captured the generated wave parameters. The study revealed that the results of numerical simulation of water wave propagation depend on the grid parameters and geometrical mesh quality.
