SPECFEM3D GLOBE

Effects due to lateral variations in compressional-wave speed, shear-wave speed, density, a 3D crustal model, ellipticity, topography and bathymetry, the oceans, rotation, and self-gravitation are all included.

The 5.1 release offers non-blocking MPI communications and includes a significant improvement in performance and a more accurate implementation of the crust. The latest version provides a perfectly load-balanced mesh for 3D mantle models honoring shallow oceanic Moho (depths less than 15 km) and deep continental Moho (depths greater than 35 km). It also accommodates European crustal models EPcrust (Molinari & Morelli, 2011) and EuCrust07 (Tesauro et al., 2008), which may be combined with global crustal model Crust2.0. Sedimentary wavespeeds are superimposed on the mesh if sediment thickness exceeds 2 km.

Additional new model routines are provided for generic point-profile models (PPM) and Gauss-Lobatto-Legendre based models (GLL). The structure of the software has been simplified to facilitate easier implementation of new 3D models. The code accommodates general moment tensor files, and provides more complete information in the SAC headers, as explained in detail in the updated user manual. New matrix-matrix multiplication routines, adapted from the book of Deville et al. (2002), help reduce the total number of memory accesses performed in each spectral element and thus significantly improve performance.
