SPECFEM3D_Cartesian simulates acoustic (fluid), elastic (solid), coupled acoustic/elastic, poroelastic or seismic wave propagation in any type of conforming mesh of hexahedra (structured or not.)

It can, for instance, model seismic waves propagating in sedimentary basins or any other regional geological model following earthquakes. It can also be used for non-destructive testing or for ocean acoustics

SPECFEM3D was founded by Dimitri Komatitsch and Jeroen Tromp, and is now being developed by a large, collaborative, and inclusive community. A complete list of authors can be found at https://specfem3d.readthedocs.io/en/latest/authors/

Instructions on how to install and use SPECFEM3D are available in the

• PDF manual located in directory: doc/USER_MANUAL

• HTML manual (latest version): specfem3d.readthedocs.io

For a quick test, run the default example with these commands:

./configure FC=gfortran CC=gcc
make all
./run_this_example.sh

and check the output files in ./OUTPUT_FILES/

NOTE: Do not modify the 'configure' script directly. Please modify the 'configure.ac' file instead, and generate a new 'configure' script with the command: autoreconf -i

• Actions tests: github actions specfem3d

• Travis tests: travis-ci specfem3d

Development is hosted on GitHub in the SPECFEM/specfem3d repository.

SPECFEM3D is a community project that lives by the participation of its members — i.e., including you! It is our goal to build an inclusive and participatory community so we are happy that you are interested in participating! We have collected a set of guidelines and advice on how to get involved in the community and keep them in the specfem3d github wiki: specfem3d wiki

SPECFEM3D is part of the software that is hosted by the Computational Infrastructure for Geodynamics (CIG). It is available on the CIG website here (SPECFEM3D).
