A numerical tour of wave propagation |

In elastic wave equation, the modulus corresponds to two Lame parameters: and , in which and denote the P- and S-wave velocity. The elastic wave equation can be written as

where (sometimes ) is stress, is particle velocity, . We display the 2 components of elastic wave propagation at , modeled with in Figure 5, in which the grid size is 200x200, the spatial interval is , and the velocities are chosen to be , .
