Technology Platform 4


Simulation and Data Visualisation

Leader: Brendon Bradley
Deputy Leader: Christopher McGann


This Technology Platform fosters the continual development of open-source software and enhances research and end-user community utilization through collaborative flagship research.  Notable examples, which span earthquake resilience pipeline, include the Open Seismic Hazard Analysis (OpenSHA) project; Southern California Earthquake Center Broadband Platform (SCEC BP) for ground motion simulation; The Open System for Earthquake Engineering Simulation (OpenSees); seismic risk assessment of infrastructure components using the Open Seismic Loss Assessment Tool (OpenSLAT), and regional seismic risk assessment of infrastructure systems using Riskscape and Measuring the Economics of Resilient Infrastructure (MERIT).


Key Thrust Areas


1: Ground motion simulations: computational pathways

Ground motion simulation: Includes the development of a computational pathway for handling ground motion simulation calculations, the necessary input model information, post-processing of results and visualisation.

  • Deliverable 1.1: 100%
  • Implement emod3d and specfem ground motion simulation software on NeSI HPC resources.
    Timeline: 1/01/2016 - 1/1/2017
  • Deliverable 1.2: 100%
  • Develop a streamlined workflow (incl. visualization) for ground motion simulation calculations to minimize the barrier to entry in new users running a large number of ground motion simulations.
    Timeline: 1/01/2016 - 31/12/2017

2: Seismic response modelling

Seismic response modelling of infrastructure: Includes both detailed modelling of individual infrastructure components (e.g. individual structural and geotechnical systems), as well as spatially-distributed infrastructure systems.

  • Deliverable 2.1: 100%
  • Optimize OpenSees FE software on NeSI HPC resources and train the QuakeCoRE community to develop a critical mass of capable OpenSees analysts.
    Timeline: 1/01/2016 - 31/12/2018
  • Deliverable 2.2: 100%
  • Develop centralized pre- and post-processing functionality for OpenSees calculations to reduce barriers to users to streamline their analyses.

  • Deliverable 2.3: 100%
  • Examine the parallelization of the OpenSees source code and look to improve its HPC scalability to enable large computational models to be run efficiently.
    Timeline: 1/01/2017 - 1/1/2019

3: Seismic loss assessment

Seismic loss assessment: Includes both detailed 'structure-specific', as well as 'regional' loss assessment.

  • Deliverable 3.1: 63%
  • Implement structure-specific and regional loss estimation software into a computational workflow with ground motion and OpenSees simulations.
    Timeline: 1/01/2017 - 31/12/2020
