| Abstract: | An efficient time-truncation algorithm applied to the boundary element solution of the two-dimensional scalar wave equation is proposed. Rational interpolation functions are here employed to compute time-domain influence matrices, in appropriate instants of time, improving previous time-truncation strategies presented in the literature. Two numerical examples are considered at the end of the paper, illustrating that the present scheme is fairly suitable for both bounded and unbounded models. |
