  A parallelized three-dimensional (3D) boundary element method is used to
simulate the interaction between an incoming solitary wave and a 3D submerged
horizontal plate under the assumption of potential flow. The numerical setup
follows closely the setup of laboratory experiments recently performed at
Shanghai Jiao Tong University. The numerical results are compared with the
experimental results. An overall good agreement is found for the
two-dimensional wave elevation, the horizontal force and the vertical force
exerted on the plate, and the pitching moment. Even though there are some
discrepancies, the comparison shows that a model solving the fully nonlinear
potential flow equations with a free surface using a 3D boundary element method
can satisfactorily capture the main features of the interaction between
nonlinear waves and a submerged horizontal plate.
