Simulations of Ground Motion in the Los Angeles Basin Based upon the Spectral-Element Method (2004, background): “It was more recently introduced for global wave propagation by Chaljub (2000) and extended for large-scale global wave propagation (Komatitsch and Tromp, 2002a,b; Capdeville et al., 2003; Chaljub et al., 2003).”
Forward and adjoint simulations of seismic wave propagation on fully unstructured hexahedral meshes (2011, methodology): “…a discontinuous formulation, one can either turn to a discontinuous version of the SEM (Bernardi et al. 1994; Chaljub 2000; Kopriva et al. 2002; Chaljub et al. 2003; Legay et al. 2005; Kopriva 2006; Wilcox et al. 2010; Acosta Minolia & Kopriva 2011) or to a discontinuous Galerkin technique.”
Spectral-element simulations of global seismic wave propagation: II. Three-dimensional models, oceans, rotation and self-gravitation (2002, methodology): “Self-gravitation, in the context of the Cowling approximation, is introduced in the SEM in a fashion similar to the innovative work of Chaljub (2000) and Chaljub et al. (2002).”
Finite-Frequency Kernels Based on Adjoint Methods (2006, methodology): “The spectral-element method (SEM) has been used extensively to simulate seismic-wave propagation on both global and regional scales (e.g., Komatitsch and Tromp, 1999, 2002a,b; Chaljub et al., 2003; Komatitsch et al., 2004).”
Full Seismic Waveform Modelling and Inversion (2011, methodology): “…on a variety of scales can be found in Faccioli et al. (1997), Komatitsch (1997), Komatitsch & Vilotte (1998), Komatitsch & Tromp (2002), Chaljub et al. (2003), Chaljub & Valette (2004) and Nissen-Meyer et al. (2007,2008) Direct solution method: The direct solution method was introduced…”
Whole-mantle radially anisotropic shear velocity structure from spectral-element waveform tomography (2014, methodology): “Using the SEM comes with numerous advantages, particularly in global-scale modelling (Komatitsch & Tromp 2002a,b; Chaljub et al. 2003), for instance: (1) accurate simulation of wave propagation in complex anisotropic and anelastic media, including treatment of phenomena often ignored by approximate…”
Global adjoint tomography: first-generation model (2016, background): “D global Earth models (Komatitsch & Tromp 2002a,b; Capdeville et al. 2003; Chaljub et al. 2003; Chaljub & Valette 2004; Peter et al. 2011).”
An hp-adaptive discontinuous Galerkin finite-element method for 3-D elastic wave modelling (2010, methodology): “(b) Same as (a) computed with SEM. clusters.”
Finite-frequency sensitivity kernels for global seismic wave propagation based upon adjoint methods (2008, methodology): “…both the forward and adjoint wavefields based upon the spectral-element method (SEM), which has been successfully applied to simulate wave propagation on both global and regional scales (e.g. Komatitsch & Vilotte 1998; Komatitsch & Tromp 1999, 2002a,b; Chaljub et al. 2003; Komatitsch et al. 2004).”
High-order finite-element seismic wave propagation modeling with MPI on a large GPU cluster (2010, methodology): “In that regard, it can be seen as a close-to-optimal hp method obtained by combining the advantages of h methods that use a dense mesh with the advantages of p methods that use high-degree basis functions (see for instance [17, 18, 19, 20, 21, 22, 23, 24], among many others).”
