The finite-difference and finite-element modeling of seismic wave propagation and earthquake motion (2007, background): “Recently, the use of the partly-staggered grid was promoted by Saenger et al. (2000); see also Saenger and Bohlen (2004), Kruger et al. (2005), Saenger et al. (2005), Bohlen and Saenger (2006).”
FFT‐based homogenization for microstructures discretized by linear hexahedral elements (2017, methodology): “For evaluating the performance of our proposed FFT-Q1Hex scheme, we use the original FFT-based scheme of Moulinec–Suquet [1, 2] and the FFTbased method of Willot [31], which is based upon rotated finite differences [65], as comparison.”
An arbitrary high-order discontinuous Galerkin method for elastic waves on unstructured meshes - IV. Anisotropy (2007, methodology): “The most widely used method, the Finite Difference (FD) method, has successfully been extended from isotropic (Madariaga 1976; Virieux 1984; Virieux 1986) to anisotropic problems using staggered (Mora 1989; Igel, Mora & Riollet 1995) or rotated staggered grids (Saenger & Bohlen 2004).”
Accuracy of heterogeneous staggered-grid finite-difference modeling of Rayleigh waves (2006, methodology): “D FD algorithms, namely (1) the widely used standard staggered grid (SSG) (Virieux, 1986; Levander, 1988; Robertsson et al., 1994; Graves, 1996; Bohlen, 2002) and (2) the more recently developed rotated staggered grid (RSG) (Gold et al., 1997; Saenger et al., 2000; Saenger and Bohlen, 2004).”
An implicit staggered‐grid finite‐difference method for seismic modelling (2009, background): “…from https://academic.oup.com/gji/article-abstract/179/1/459/740798 by guest on 29 July 2018 medium containing cracks, pores or free surfaces (Saenger & Shapiro 2002); anisotropy (Saenger & Bohlen 2004; Bansal & Sen 2008) and scattering and diffraction by a single crack (Krüger et al.…”
