SimCenter: A computational framework to simulate the impacts of natural hazards

This webinar will introduce ‘SimCenter* cyberinfrastructure framework’, which provides easy access to various advanced modeling/analysis techniques required to simulate the impact of natural hazards (earthquake, hurricane, storm surge, and tsunami) to both researchers and practitioners. After a brief overview of the framework and supported modules, two example workflows are introduced and demonstrated using open-source desktop applications developed in SimCenter: (1) surrogate modeling of seismic structural response and (2) regional resilience assessment.
In the first part, we will introduce the motivation and methodology of surrogate modeling for seismic risk assessment. The focus will lie on Gaussian Process-based surrogate modeling of structural response subjected to earthquake. To demonstrate the example, the EE-UQ software tool will be utilized.
In the second part, a workflow and research software (R2D) for high-resolution assessment of disaster impact and risk on a regional scale will be introduced. The R2D tool facilitates importing and querying data describing multiple types of regional hazard and infrastructure systems. It helps researchers with setting up and running the simulations either on their local computer or at the HPC clusters available at DesignSafe. The workflow will be demonstrated with a use case of regional seismic risk analysis.
 The audiences are encouraged to download and try the desktop software applications EE-UQ and R2D tool in advance so that they can follow the demonstration example during the presentation and ask trouble-shoot questions during the Q&A session.
