In Exact non-reflecting boundary conditions by Keller and Givoli, an exact boundary condition is devised for the numerical solution of the reduced wave equation in an infinite domain, using the finite element region without error. This work has been extended to other equations, including those for elastic waves, and small test problems have shown that method is very effective.
