Description

The purpose of the present study is to newly propose a numerical wave tank by introducing a wave generation source into a CADMAS-SURF/3D and verify the validity of the numerical wave tank. The numerical experiments with the change of the coefficient α, which is related to the strength and extensity of wave generation source, revealed that the most appropriate waves are able to be generated in the case of α=2. The applicability of the proposed numerical wave tank was confirmed by applying it to oblique wave generation problems and comparing the numerical results with the results of the laboratory experiment on wave deformation under Tsunami action.
