Abstract : Discontinuous Galerkin finite element schemes exhibit attractive features for large-scale wave-propagation simulations on modern parallel architectures. In order to limit the size of the computational domain, these schemes must be coupled with nonreflective boundary conditions, which remains a challenging task. In this talk, we present a coupling of high-order absorbing boundary conditions with nodal discontinuous Galerkin schemes. Numerical results are proposed to validate both the accuracy and the computational efficiency of the techniques.
