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 4.0 release involves major improvements to the mesh. Using a new doubling brick, the mesh is now more accurate (in particular in the upper and mid-mantle) and also perfectly load-balanced when running on a parallel computer, and therefore the package should scale very well all the way up to the petascale. A very large number of CPUs can now be used. Most 1D Earth models are available (PREM, IASP91, 1066A, AK135, and REF), and in addition to 3D model S20RTS, this version also accommodates model S362ANI.
