A modiÿed version of an exact Non-re ecting Boundary Condition (NRBC) ÿrst derived by Grote and Keller is implemented in a ÿnite element formulation for the scalar wave equation. The NRBC annihilate the ÿrst N wave harmonics on a spherical truncation boundary, and may be viewed as an extension of th

When solving the wave equation in in®nite regions using ®nite element methods, the domain must be truncated. We investigate the accuracy of time-dependent non-re¯ecting boundary conditions (NRBC) derived in Grote, Keller (1995), when implemented in the ®nite element method. The NRBC annihilate the ®
