Computational Infrastructure for Geodynamics

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.

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

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.

vq

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

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.

pylith_benchmarks

Benchmark data and results for PyLith.

pylith_installer

Installer code for PyLith.

software_template

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

spatialdata

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

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.

citcomcu

CitcomCU is a finite element parallel code capable of modeling thermochemical convection in a three dimensional domain appropriate for convection within the Earth's mantle.

conman

ConMan is a finite element program for the solution of the equations of incompressible, infinite-Prandtl number convection in two dimensions, originally written by Scott King, Arthur Raefsky, and Brad Hager.

pythia

Pythia refers to the Pyre framework and a collection of packages that interact with it, such as an interface to the ACIS solid modeling package.

autoconf_cig

Autoconf M4 macros for CIG codes

pylith_parameters

Web application for viewing and editing PyLith parameters.

cig_backend

CIG Backend Code

pylith-tutorials

cig_tools

Various tools for CIG and CIG projects

nemesis

Nemesis is required for PyLith. Nemesis simply installs a pair of Python interpreters ('nemesis' and 'mpinemesis') which incorporate MPI and include Pythia's "_mpi" module.
