3DPSTM: 3-D Kirchhoff Prestack Time Migration 3DGeo's 3-D Kirchhoff prestack time migration (3DPSTM) package is based on a state-of-the-art implementation of the algorithm designed to achieve maximum efficiency on parallel-vector and cache-based supercomputers. The algorithm includes several choices of anti-aliasing and an amplitude equalization operator to preserve the amplitude information in the final image even when the spatial sampling of the input data is irregular. Through scaling of the input and output data 3DPSDM can be run on workstations as well as supercomputers, though the best efficiency is obtained on larger computing platforms. The 3DPSTM implementation handles both straight and curved rays.

This robust implementation of the Kirchhoff Method provides excellent solutions for imaging complex faults, intrusives and overthrusts. The enhanced imaging and ability to produce preserved amplitude offset-dependent data for AVO plays a significant role in improving exploration success.

The CIG Model Analyzer (Cigma) is a program designed to compare general numerical models. In particular, Cigma will calculate the L2-norm of the difference between finite element models, resulting in approximate global and local error metrics that may be used for both code verification and benchmarking purposes. CIG developed Cigma in response to demand from the short-term tectonics community for an automated tool that can perform rigorous error analysis on their finite element codes

CitcomS is a finite element code designed to solve thermal convection problems relevant to earth’s mantle released under the GNU General Public License. Written in C, the code runs on a variety of parallel processing computers, including shared and distributed memory platforms. In an effort to increase the functionality of CitcomS to include greater control during simulations on large parallel systems, the software has been reengineered from previous versions of CitcomS to work with a Python-based modeling framework called Pyre. With Pyre, CitcomS can be dynamically coupled with other CitcomS simulations or with other codes such as SNAC, which solves crustal and lithospheric problems.

Dynamo codes represent a powerful new tool for the quantitative study of a broad range of geophysical processes, ranging from short time-scale phenomena such as magnetic variations, rotational variations, and flow in the core, to long-term phenomena such as magnetic excursions, reversals, superchrons, and the evolution of the core and its thermal and chemical interaction with the mantle. The primary objective of CIG in this area is to provide the Earth Science community with robust, reliable, efficient, flexible, stateof- the-art numerical codes for modeling dynamo processes in the Earth’s core and in the interiors of other planets. Another CIG objective is to support graphical- and user-interfaces for these codes that allow Earth scientists to analyze, display, and interpret dynamo code results, and to compare results from the various codes that we support, as well as with geomagnetic, space magnetic, and paleomagnetic data. http://geodynamics.org/cig/software/packages/geodyn/mag/
Simulation of the marine environment has become an important tool across a wide range of human activities, with applications in coastal engineering, offshore industries, fisheries management, marine pollution monitoring, weather forecasting and climate research to name but a few. Sustainable management of the ecological resources of coastal environments demands an ability to understand and predict the behavior of the marine ecosystem. Thus, it is highly desirable to extend the capabilities of existing hydrodynamic models to include chemical, bio-geo-chemical and biological processes within the marine ecosystem.

SNAC (StGermaiN Analysis of Continua) is an updated Lagrangian explicit nite dierence code for modeling a nitely deforming elasto-visco-plastic solid in 3D, released under the GNU General Public License. In this code, nodal velocities satisfying a weak-form of the momentum balance are obtained as the nodal solution. SNAC shares a mathematical foundation, and thus major advantages, with a standard finite element method (FEM). However, it departs from the FEM by not making explicit use of shape functions. A Cartesian mesh consisting of 4-node linear or constant-strain tetrahedral elements is used to represent a discretized domain, although a spherical domain can also be used. On top of the tetrahedral discretization, a coarser discretization is constructed by zones, which are defined by eight nodes like a hexhedral element in the standard FEM and subdivided into two layouts of five tetrahedral elements for symmetric response. To avoid the over-stiff response of tetrahedrons in the incompressible limit, mixed discretization is applied. The mixed discretization relieves over-stiness by replacing the first invariant of tetrahedral strain-rate tensor with the one averaged over a zone.

The software package SPECFEM3D simulates southern California seismic wave propagation based upon the spectralelement method (SEM). Effects due to lateral variations in compressional-wave speed, shear-wave speed, density, a 3D crustal model, topography and bathymetry are included.
The package can accommodate full 21-parameter anisotropy as well as lateral variations in attenuation. Adjoint capabilities and finite-frequency kernel simulations are included. All SPECFEM3D software is written in Fortran90, and conforms strictly to the Fortran95 standard. It uses no obsolete or obsolescent features of Fortran77. The package uses parallel programming based upon the Message Passing Interface (MPI).

Underworld is a 3D-parallel geodynamic modelling framework capable of deriving viscous / viscoplastic thermal, chemical and thermochemical models consistent with tectonic processes, such as mantle convection and lithospheric deformation over long time scales.
Underworld utilises a Lagrangian particle-in-cell finite element scheme (the prototype of which is the Ellipsis code), and is visualised using gLucifer.
The Underworld source code is written in C in an Object Oriented style, following the methodology of design for change applied to computational codes implemented in StGermain. It uses PETSc (optimised numerical solvers) and MPI (parallelism) libraries. The Underworld to StGermain software stack is released under a mixture of BSD and LGPL licenses.
The Underworld Modelling Capabilities details the core set of phenonema modelled and distributed with Underworld, including lithospheric deformation, slab subduction and mantle convection. Underworld can be obtained from Underworld Downloads, and user and developer documentation from Underworld Documentation.
A prevalent example of the application of the Underworld platform is the CIG GALE code, which solves problems related to orogenesis, rifting, and subduction with coupling to surface erosion models.
Underworld is under collaborative development by Monash University and VPAC, as part of the Victorian node of the NCRIS AuScope 'Simulation, Analysis, Modelling' capability.
