Elastic Mimetic Finite-differences in the Presence of Topography

Proceedings, 2013
Finite-differences (FD) are the most popular schemes for seismic modelling. For elastic problems, staggered-grid FD offers many advantages in terms of accuracy and efficiency. However, FD methods typically struggle at modelling seismic waves in the presence of a non-flat topography.

3D Seismic Modelling With Topography Using Mimetic Finite-Differences

SEG Technical Program Expanded Abstracts 2013, 2013
We present a novel FD scheme which can solve accurately elastic wave propagation in the presence of topography in 3D. It is based upon a Fully Staggered Grid and employs grid deformation and mimetic operators to obtain results with very few points per wavelength when compared to other similar approaches.

M-Adaptation in the mimetic finite difference method [PDF]

Mathematical Models and Methods in Applied Sciences, 2014
The mimetic finite difference method produces a family of schemes with equivalent properties such as the stencil size, stability region, and convergence order. Each member of this family is defined by a set of parameters which can be chosen locally for every mesh element. The number of parameters depends on the geometry of a particular mesh element. M-

Mimetic finite-difference coupled-domain solver for anisotropic media

GEOPHYSICS, 2021
Accurately modeling full-wavefield solutions at and near the seafloor is challenging for conventional single-domain elastic finite-difference (FD) methods. Because they treat the fluid layer as a solid with zero shear-wave velocity, the energy partitioning for body and surface waves at the seafloor is distorted.
