- Update of EFISPEC3D source code (r322): bug correction for viscoelastic simulation only, fixing the initialization of the variable 'rg_mem_var_exp' when the time step is not defined in file *.cfg. See Download Section
February 16th, 2015
- Update of EFISPEC3D source code (r321). See Download Section
January 20th, 2015
- Update of EFISPEC3D source code (r318). New features: - Better computation of free surface receivers.
- Read ExodusII mesh files.
- Auto-compute stable time step.
- Snapshot volume box in VTK format (by converting GLL nodes to VTK hexa8 mesh).
- Under development: medium homogenization based on Moczo et al. 2002.
January 6th, 2015
- A new release of EFISPEC3D is coming soon. New features: read ExodusII mesh files, auto-compute stable time step, snapshot volume box in VTK format (by converting GLL nodes to VTK hexa8 mesh).
- EFISPEC3D is an open-source code: Any feedbacks (bugs, developments, etc.) on previous releases would be much appreciated!

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 FORTRAN95 and MPI to run on parallel architectures. It is under a double license: CeCILL V2 and GNU GPL V3.
