SNAC (StGermaiN Analysis of Continua) is an updated Lagrangian explicit finite difference code for modeling a finitely deforming elasto-visco-plastic solid in 3D.

aspect

A parallel, extensible finite element code to simulate convection in both 2D and 3D models.

pylith

PyLith is a finite element code for the solution of dynamic and quasi-static tectonic deformation problems.

sw4

SW4 (Seismic Waves, 4th order) implements substantial capabilities for 3-D seismic modeling, with a free surface condition on the top boundary, absorbing super-grid conditions on the far-field boundaries, and an arbitrary number of point force and/or point moment tensor source terms.

seismic_cpml

SEISMIC_CPML is a set of sixteen open-source Fortran90 programs to solve the two-dimensional or three-dimensional isotropic or anisotropic elastic, viscoelastic or poroelastic wave equation using a finite-difference method with Convolutional or Auxiliary Perfectly Matched Layer (C-PML or ADE-PML) conditions, developed by Dimitri Komatitsch and Roland Martin from CNRS, France.

axisem

AxiSEM is a parallel spectral-element method to solve 3D wave propagation in a sphere with axisymmetric or spherically symmetric visco-elastic, acoustic, anisotropic structures.

Rayleigh

Rayleigh: Pseudo-spectral MHD

burnman

BurnMan is a library for modeling mantle thermodynamics and thermoelasticity constrained by mineral physics experiments.

CitcomS is a finite element code designed to solve compressible thermochemical convection problems relevant to Earth's mantle.

relax

Relax implements a semi-analytic Fourier-domain solver and equivalent body forces to compute quasi-static relaxation of stress perturbation.

mineos

Mineos computes synthetic seismograms in a spherically symmetric non-rotating Earth by summing normal modes.

selen

SELEN: a program for solving the "Sea Level Equation".

calypso

Calypso performs magnetohydrodynamics (MHD) simulation in a rotating spherical shell, modeled as Boussinesq fluid driven by thermal or compositional buoyancy.

best_practices

Software development and training best practices.

plasti

Plasti is a 2D ALE (Arbitrary Lagrangian Eulerian) code donated to CIG by Sean Willett and Chris Fuller of the University of Washington. The code originated at Dalhousie University in Canada.

hc

HC is a global mantle circulation solver following Hager & O'Connell (1981) which can compute velocities, tractions, and geoid for simple density distributions and plate velocities.

vq

Virtual Quake is a boundary element code designed to investigate long term fault system behavior and interactions between faults through stress transfer.

pylith_benchmarks

Benchmark data and results for PyLith.

pylith_installer

Installer code for PyLith.

ellipsis3d

Ellipsis3d is a three-dimensional version of the particle-in-cell finite element code Ellipsis, a solid modeling code for visco-elastoplastic materials. The particle-in-cell method combines the strengths of the Lagrangian and Eulerian formulations of mechanics while bypassing their limitations.

mag

MAG is a serial version of a rotating spherical convection/magnetoconvection/dynamo code, developed by Gary Glatzmaier and modified by Uli Christensen and Peter Olson.

software_template

This is an example repository that follows the best software practices of the Computational Infrastructure for Geodynamics (CIG)

SpatialData provides an interface to Proj.4 (cartographic projections library) for converting coordinates among a variety of geographic projections.

sw4lite

Testing numerical kernels in SW4

flexwin

The FLEXWIN software package automates the time-window selection problem for seismologists. It operates on pairs of observed and synthetic single component seismograms, defining windows that cover as much of a given seismogram as possible, while avoiding portions of the waveform that are dominated by noise.
