3‐D finite‐difference, finite‐element, discontinuous‐Galerkin and spectral‐element schemes analysed for their accuracy with respect to P‐wave to S‐wave speed ratio (2011, methodology): “Here, we consider a nodal DG scheme with the centred flux (Etienne et al. 2010) and we restrict to two of the simplest formulations.”
Forward and adjoint simulations of seismic wave propagation on fully unstructured hexahedral meshes (2011, background): “…et al. 2006; Bernacki et al. 2006; Dumbser & Käser 2006; De Basabe et al. 2008; de la Puente et al. 2009; Wilcox et al. 2010; De Basabe & Sen 2010; Etienne et al. 2010), with optimized efficiency because of its tensorized basis functions (Wilcox et al. 2010; Acosta Minolia & Kopriva 2011).”
