Introducing EFISPEC
EFISPEC stands for "Element-FInis SPECtraux".
EFISPEC3D is a free code that solves the three-dimensional wave equations using a spectral-finite-element method (SFEM); commonly called spectral-element method (SEM).
EFISPEC3D is programmed in FORTRAN08 and MPI to run on parallel architectures. It is under a double license: CeCILL V2 and GNU GPL V3.
