The Regional Resilience Determination (R2D) application facilitates high-resolution assessment of disaster impacts 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 R2D 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 resources at DesignSafe. Once the simulations are completed, the main results are visualized in the tool, and detailed results are 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:

See the application'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.
