*PML COEFFICIENT

Specify perfectly matched layer coefficients.

This option can be used only as a suboption of the PERFECTLY MATCHED LAYER option. It is used to specify the coefficients to be used in the perfectly matched layer (PML) to model infinite domains.

VARIATION

Set VARIATION=LINEAR to define a linear variation of the PML coefficients from zero at the interface of the acoustic and perfectly matched layer domains to the prescribed value at the outer surface of the perfectly matched layer domain.
