摘要：

The main theoretical relations obtained via application of the finite-difference time-domain (FDTD) method to a 2D acoustic problem are considered within the framework of a model taking into account the anisotropy of elastic properties and the internal friction. A computational algorithm is proposed that realizes a two-fold FDTD calculation scheme and allows the calculation of wave processes in problems with arbitrary complex boundary conditions.
