Regional Resilience Determination (R2D) Tool (Version 4.2.0)



The Regional Resilience Determination Tool (R2D) is a graphical user interface for the SimCenter application framework designed to simulate the regional impact of hurricanes and earthquakes. R2D advances the capabilities of the natural hazards engineering community by facilitating the high-resolution assessment of disaster impact and risk on a regional scale. Researchers can investigate disaster scenarios or perform a probabilistic assessment by considering a diverse set of plausible events and propagate the uncertainty in the hazard and the characteristics of the built environment through the simulations.

The user interface of the R2D Tool facilitates importing and querying input data that describes the regional hazard and the built environment and helps researchers with setting up and running the simulations either on their local computer or at the HPC clusters available at DesignSafe. Once the simulations are completed, the main results are visualized in the tool and detailed results are also available for post processing.

Be sure to update to this new version as older versions will not run at DesignSafe due to changes in the backend.

Several examples are provided to demonstrate the application's versatility when it comes to assembling simulation workflows of various levels of complexity:

  • E1 - Basic HAZUS
  • E2 - MDOF Building Response
  • E3 - Physics-based Ground Motions
  • E4 - OpenSeesPy FEM
  • E5 - Ground Shaking + Liquefaction
  • E7 - Hurricane Wind + Water
  • E8 - Hurricane Wind
  • E9 - Tsunami
  • E10 - Site Response Analysis
  • E12 - Istanbul Regional Seismic Risk Analysis
  • E14 - Basic HAZUS Transportaton Infrastructure

See the Tool's Documentation for details on these examples.

R2D is built on the SimCenter's Application Framework, which presents opportunities for community development and contributions to enhance simulation capabilities and tackle complex scientific questions in natural hazards research.
