Description
In this study, we examined the validity of numerical computation by applying two different assumptions, hydrostatic and non-hydrostatic assumptions, with the change in mesh aspect ratio. Tokyo Bay was chosen as an example of an enclosed bay in order to investigate internal wave breaking over a slope. We applied 6 different mesh aspect ratios, 5, 10, 25, 50, 100 and 500. As a result, it is found from non-hydrostatic computations that the larger the aspect is, the larger the numerical error appears. In contrast to the non-hydrostatic computations, the numerical error is found to be the same in the all mesh aspect ratios. Additionally, it is revealed that mesh aspect ratio should be less than 10 in non-hydrostatic computations.
