“…A particular FE scheme is the spectral-element (SE) method, which is state-of-the-art in regional and global earthquake simulations at the moment (e.g., Priolo et al, 1994;Komatitsch, 1997;Seriani, 1998;Chaljub, 2000;Capdeville et al, 2003;Nissen-Meyer et al, 2008;Fichtner et al, 2009;Cupillard et al, 2012). The SE method supports computational grids of deformable hexahedral elements, to simulate fully 3-D wavefields with high-order spatial accuracy, and explicit time extrapolation schemes.…”
