The Computational Infrastructure for Geodynamics (CIG) 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.[1]

CIG is located at the University of California, Davis, and is a member-governed consortium with 50 member institutions and 13 international affiliates.

Software packages currently supported [2] include:

  • Computational Science: Geodynamics AMR Suite (Deal.II), Exchanger, Cigma, and Pythia/Pyre.
  • Computational Seismology: SPECFEM3D_GLOBE, SPECFEM3D, SPECFEM2D, SPECFEM1D, SEISMIC_CPML, Flexwin, and Mineos.
  • Geodynamo: Calypso, MAG
  • Long-Term Crustal Dynamics: Gale,[3] Plasti, and SNAC[4]
  • Mantle Convection: CitcomCU, CitcomS, ASPECT (an adaptive mesh refinement code based on Deal.II), Ellipsis3d,[5] based on Citcom, and ConMan, and HC
  • Short-Term Crustal Dynamics: PyLith, RELAX, SELEN, and LithoMop


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.
