Transparent Boundary Conditions for the Elastic Waves in Anisotropic Media

•A novel approach to generate numerical LRBCsfor anisotropic time-domain wave propagation problems is proposed and implemented in 2D•LRBCsare efficient in both isotropic and anisotropic media, including the case where PML approach fails (case IV)•LRBC operator does not depend on the meshing inside the computational domain•LRBC efficiency (amplitude of reflected waves) can be automatically controlled during generation of the operator•It is possible to generate in advance a library of LRBC matrices for given media parameters and geometry of computational domain•The algorithm is highly parallelized
