Abstract
In this study, numerical experiments were performed to decide the proper size of a finite elementfor the analysis of harbor resonance problems. Various sizes of finite elements were considered from 1/3 to 1/60of wavelength to model a fully opened rectangular harbor. Through the numerical results, the proper number offinite elements per wavelength were revealed to be nine within two percents errors allowed in resonant periodand amplification ratio, while twelve within one percent error. It was found that eror rates of resonant periodsdecrease linearly, while those of amplification ratio decrease with oscilating form as the size of an elementdecreases. The eror of amplification ratio increases more rapidly than that of resonant period in case of elementnumbers below nine.
