Non-reflecting boundary conditions for 2 Danisotropic elastodynamics

Our numerical method of generating the boundary operator is based on conception of both analytical and discrete transparent boundary conditions. The elastic wave propagation in 2D orthotropic media is considered to show transparency of open circular boundary with proposed NRBC for all tested cases, even where PML approach fails.
