A three dimensional numerical wave tank (NWT) based on a higher order boundary element method (BEM) is developed. Nonlinear periodic waves can be generated at one end of NWT, and reflective or absorbing boundary conditions are specified on the other end and lateral boundaries. The model solves fully nonlinear potential flow equations with a free surface using a HOBEM, in which boundary geometry and field variables are represented by 16-node cublic quadrilateral elements developed by Grilli, et al.(2001) and a mixed Eulerian-Lagrangian time updated with the second-order explicit Taylor series expansions in used. The computational results show that the NWT can be used to simulate nonlinear water wave propagation efficiently with good numerical accuracy and convergence with a refined spatial-temporal discretization.
