Parallel Modelling Framework for Geoscience Research

Underworld is a StGermain parallel modelling framework for Geoscience research codes, which utilises a Lagrangian particle-in-cell finite element scheme and is visualised using gLucifer, a general visualisation framework based upon the foundation and domain components of StGermain.

Underworld was developed with Professor Louis Moresi's Geodynamics group at Monash University, originally as part of the completed Australian Computational Earth Systems Simulator (ACcESS) Snark and Data-assimilation projects. It is now part of the NCRIS AuScope capabilty in the Simulation and Modelling program.

Underworld is the most mature of the StGermain derived framework, CSD's core computational mechanics technology. It forms the basis for the CIG GALE and MADDs projects, and is the foundation of the Deakin University Xanthus project.

• 3D Parallel, community based open source Geodynamics code and framework
• Capable of Convection and Deformation modelling
• Has own visualisation software called gLucifer
• Written in C, but in an Object Oriented style
• Uses PETSc libraries for optimised numerical solvers
• Uses MPICH libraries for parallelism.
