Abstract

Abstract

An efficient finite element method for solving mild-slope equation is proposed.When solving the mild-slope equation,a spongy layer is used.The diffraction potential is subtracted from the total velocity potential at the incident boundary by using discontinuous elements.The error and numerical reflection due to using radiation boundary condition are reduced efficiently because the po tential function is damped at the spongy layer through adding a friction parameter into the mild-slope eqauation.
