The problems of wave field modeling with finite element method in unbounded domains and methods to deal with them are analyzed. To obtain optimal solution, using of infinite elements is proposed on the boundaries of the modeled area combined with standard finite-element modeling inside the area. It is important however to choose the shape functions of infinite elements depended on the conditions of wave decay at infinity.
