In the present study, the meshless generalized finite difference method (GFDM) together with the second-order Runge-Kutta method (RKM2) is employed to construct a fully three-dimensional (3D) meshless numerical wave flume (NWF). Three numerical examples, i.e., the propagation of freak waves, irregular waves and focused waves, are implemented to verify the accuracy and stability of the developed 3D GFDM model. The results show that the present numerical model possesses good performance in the simulation of nonlinear water waves and suggest that the 3D "RKM2-GFDM" meshless scheme can be adopted to further simulate more complex nonlinear problems regarding wave-structure interactions in ocean engineering. |
