In this study, we propose a new numerical method, named as Traction Image method, to
accurately and efficiently implement the traction-free boundary conditions in finite difference …

Surface topography has been considered a difficult task for seismic wave numerical
modelling by the finite-difference method (FDM) because the most popular staggered finite …

We present a discrete modelling scheme which solves the elastic wave equation on a grid
with vertically varying grid spacings. Spatial derivatives are computed by finite‐difference …

The conventional finite-difference (FD) method often suffers from numerical dispersion when
too few samples per wavelength are used or when models have large velocity contrast, or …

To simulate seismic wave propagation in the spherical Earth, the Earth′ s curvature has to
be taken into account. This can be done by solving the seismic wave equation in spherical …

The velocity‐stress formulation for propagation of elastic seismic waves through 2D
heterogeneous transversely isotropic media of arbitrary orientation is presented. The …
