PML (Perfectly Matched Layers)

The perfectly matched layer (PML) is a domain or layer (sometimes called sponge layer) that is added to an wave model to mimic an open and nonreflecting infinite domain. It sets up a perfectly absorbing domain as an alternative to nonreflecting boundary conditions.
More math detail can be found here.[1]

Symmetry

The symmetry condition can effectively reduce the computation of simulation. The rule of symmetry is mathematics thing. So, let me just know the result.
