A modiรฟed version of an exact Non-re ecting Boundary Condition (NRBC) รฟrst derived by Grote and Keller is implemented in a รฟnite element formulation for the scalar wave equation. The NRBC annihilate the รฟrst N wave harmonics on a spherical truncation boundary, and may be viewed as an extension of th
A discrete non-local (DNL) boundary condition is used to solve the water waves propagation problem over variable depth. This condition is obtained by means of full solution of the discrete Helmholtz operator in a structured network. We consider a simulation of wave propagation around a circular isla
When solving the wave equation in inยฎnite regions using ยฎnite element methods, the domain must be truncated. We investigate the accuracy of time-dependent non-reยฏecting boundary conditions (NRBC) derived in Grote, Keller (1995), when implemented in the ยฎnite element method. The NRBC annihilate the ยฎ
