The Regional Resilience Determination Tool (R2D app) creates and launches simulation workflows to assess the regional impact of natural hazard events. Advanced capabilities facilitate high-resolution simulation. Researchers can investigate disaster scenarios or perform a probabilistic assessment by including uncertainties in both the hazard and the characteristics of the built environment. Assessments can include a comprehensive inventory of assets or focus on a distributed portfolio of structures, subjected to hurricanes, earthquakes, or other hazard events. The application integrates tools and libraries to support the creation of inventories, characterize hazard events, and simulate damage and losses on large inventories of buildings and civil infrastructure. User-defined models and calculation methodologies are also supported. Detailed results are provided in a standardized format to facilitate post-processing and further calculations to evaluate community impacts and recovery. The computations are performed by a simulation workflow that runs on either the user’s local machine or on a high-performance computer made available by DesignSafe.

This document covers the features and capabilities of Version 4.1 of the tool. Users are encouraged to comment on what additional features and capabilities they would like to see in future versions of the application through the Message Board.
