Description
AxiSEM is a parallel spectral-element method for 3D (an-)elastic, anisotropic and acoustic wave propagation in spherical domains. It requires axisymmetric background models and runs within a 2D computational domain, thereby reaching all desired highest observable frequencies (up to 2Hz) in global seismology. The Fortran2003 (OpenMP, MPI) code scales very well on supercomputers and is available under the GPL license. For more details see the website at www.axisem.info.
