Abstract We present a method to realize viscoelastic boundary condition in ANSYS finite element software by using the Combin 14 element.The numerical results show that the method can well absorb the boundary reflection wave,and is insensitive to change of boundary normal stiffness parameters while the tangential stiffness parameters keep constant,and vice versa.The results also verify the effectiveness and stability of the method.
