3.3 Effect of Grid Density
Figure 3 displays the wave profiles along the hull surface and the wave contours at two grid levels only
for the KCS model and the DTMB 5415 model, where the origin (x/L=O.O) is at the midship and the
bow is located at x/L=-O.S. The wave patterns close the hull surface are well correlated with the
measurements. Furthermore, the results indicate that the influence of the two grid levels on the near-
wall waves is weak. It is obvious that the results at the fine mesh are closer to the experimental data.
