Provides a practical approximation for nonreflecting boundary conditions in wave propagation simulations, but the contribution is incremental.
The paper derives truncated transparent boundary conditions for hyperbolic systems, enabling local approximate nonreflecting boundaries. Examples are given for 3D elasticity and Biot poroelasticity.
We derive equations for evaluating differential operators in transparent boundary conditions (TBCs) for a certain class of hyperbolic systems of second-order equations. This local part of TBCs can be used as approximate nonreflecting boundary conditions. We give examples of obtaining such truncated TBCs for 3D elasticity and Biot poroelasticity
