A: Normalized particle velocities at y = 8.5 mm simulated by the implemented pseudo-spectral method and a FEM method. The material is a transversely isotropic, elastic medium with ${\mu }_1^x=25\mathrm{kPa}$ and ${\mu }_1^y=9\mathrm{kPa}$. The mesh density in the plane of symmetry for the FEM method is 30% higher than that of the pseudo-spectral method. B: Percentage of change of the maximum particle velocity at y = 8.5 mm relative to the finest mesh density.
