Exact integrodifferential boundary conditions for finite chains and half-spaces are obtained by means of Green's functions for initial value problems. Truncating the resulting integrals in time, we obtain absorbing boundary conditions. Numerical tests illustrate the ability of these conditions to suppress reflections.engjournal articlehttps//doi.org/10.1016/j.jcp.2009.11.013http://www.sciencedirect.com/science/article/pii/S0021999109006329restricted access530.1517.95Molecular-dynamicsHyperbolic systemsAbsorbing layerSimulationsPropagationEquationsNonreflecting boundary conditionsGreen's functionsLattice modelsDiscrete wave equationsTransparent boundary conditionsAbsorbing boundary conditionsDirichlet-to-Neumann operatorsMolecular dynamicsFísica matemáticaEcuaciones diferenciales1202.07 Ecuaciones en Diferencias
