Regional Resilience Determination (R2D) Tool (Latest Version 1.0.0)


The Regional Resilience Determination Tool (R2D) is a graphical user interface for the SimCenter application framework designed to simulate the regional impact of natural hazards. 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. 

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

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

The current version allows users to investigate the performance of the buildings in the region when subjected to earthquake events. The application is being expaned to allow researchers to investigate the effects of a hurricane event, and future versions will incorporate lifelines and respond to users' feature requests. Interested beta testers should contact

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.
