The AuScope Simulator is a toolkit of simulation, modelling, inversion and data mining tools, underpinned by parameters provided through the AuScope Earth Composition and Evolution component. The AuScope simulator makes extensive use of software, techniques and expertise developed through the Australian Computational Earth Systems Simulator (ACcESS) Major National Research Facility.
The NCRIS funds will be used principally for deployment, maintenance and enhancement of software previously developed in the participating institutions of the ACcESS MNRF and Predictive Mineral Discovery (pmd*CRC) activities and will include the following.
Data inference and inversion
The ANU Terrawulf cluster for processing of raw geospatial and Earth Imaging data was upgraded.
Escript is a highly innovative, object-oriented language for solving partial differential equations using high performance computers. Escript has application across a broad range of the sciences and underpins many of the problem-specific software tools developed in the ACcESS MNRF.
Particle modelling is a specialized area with particular application to materials and earth science. This code was developed initially for rock failure research related to geohazards and the modelling of blockcaving techniques for mining.
These codes are being applied to earthquake and tsunami modeling in the ongoing quest to predict and ameliorate the effect of these catastrophic events. The codes are also being applied to the modeling of the complex interactions of fracture and heat transfer for the production simulation of geothermal power from hot fractured rocks.
The focus here is to provide a capability for researchers to tailor solutions to a range of problems, using Escript. These codes have also found an application in the production of ceramics.
These codes have been developed to produce a suite of tools that can be used by researchers to simulate large scale Earth processes, such as plate/mantle interaction and basin development. The latter is of particular interest to energy exploration companies.
Surface Process Model
The first stage of parallelising a code that does not easily lend itself to this mode of deployment has met with success. This will enable the tool to be applied to more complex and realistic erosion, sediment transport and basin fill problems.
Pplates is a tectonic reconstruction tool for linking plate motion histories with geodynamic, tectonic and surface elevation outcomes. The what if approach encapsulated in the Pplates software is designed to provide the structural geologist with quantitative feedback on the validity of postulated scenarios.
This investment is designed to facilitate the publishing of map data across the group in a consistent way. The investment will leverage the extensive capabilities of the Open Source GMT mapping software with custom links designed to present structural geological model map outputs for time based evolutionary models.
A code developed within CSIRO Exploration & Mining and the Minerals Down Under Flagship and was started during the pmd*CRC using Fastflo and more recently the UQ Escript solver. The code models coupled fluid-flow, heat and mass transport and chemical reactions (using the HCh/WinGibbs solver) within the earth, and will be of widespread interest in the minerals and energy industries.
ANUGU Tsunami Inundation Code
ANUGA is an implementation of a hydrodynamic model that is specifically designed to model the process of coastal inundation from hydrological disasters such as tsunami or storm surge. ANUGA is a joint development project between GA and the ANU.
