Developing serpent-type wave generators to generate solitary waves in a 3D-basin was investigated in this study.Based on the Lagrangian description with time-marching procedures and finite differences of the time derivative,a 3D multiple directional wave basin with multidirectional piston wave generators was developed to simulate ocean waves by using BEM with quadrilateral elements,and to simulate wave-caused problems with fully nonlinear water surface conditions.The simulations of perpendicular solitary waves were conducted in the first instance to verify this scheme.Furthermore,the comparison of the waveform variations confirms that the estimation of 3D solitary waves is a feasible scheme.
