Abstract

Suppression of boundary reflections is a critical issue in numerical simulation of elastic waves. For this purpose, many processing approaches of boundary are worked out. One of ideal methods is PML, which has been used widely. This paper uses PML absorbing boundary condition in the simulation of full seismic wavefields. Numerical experiments showed that the thickness of PML for qSV and qSH waves is larger than P wave, 13 grid points is appropriate.
