Computational Infrastructure for Geodynamics

The Computational Infrastructure for Geodynamics (CIG) is a community-driven organization that advances Earth science by developing and disseminating software for geophysics and related fields. It is a National Science Foundation-sponsored collaborative effort to improve geodynamic modelling and develop, support, and disseminate open-source software for the geodynamics research and higher education communities.

CIG is located at the University of California, Davis, and is a member-governed consortium with 59 institutional members and 15 international affiliates.

History

CIG was established in 2005 in response to the need for coordinated development and dissemination of software for geodynamics applications. Founded with an NSF cooperative agreement to Caltech, in 2010, CIG moved to UC Davis under a new cooperative agreement from NSF.

CIG hosts codes in a wide range of disciplines in geodynamics and computational science. The following is a list of software packages that are developed by CIG, developed by community contributors, supported by CIG, or supported by community contributors:
