Abstract

Abstract

Here the displacement method for the simulation of water waves was studied. Under the physical coordinate system, the displacements were taken as the unknown variables. Under the assumption of small deformation, the water incompressibility was satisfied through introduction of the flow function. Hence the variational principle of the analytic mechanics can be applied and the numerical results can be more conveniently got by efficient means of the interbelt finite element method, the canonical transformation and the symplectic conservation integration. 2 numerical examples show the correctness and potential of the proposed method.
