The Hydro-UQ Application is open-source software that provides researchers a tool to assess the performance of a building subjected to wave loading due to tsunami and storm surge. The tool facilitates a multiscale coupling by resolving areas of interest by coupling two-dimensional shallow water solver (GeoClaw) with three-dimensional CFD solver (OpenFOAM) through an interchangeable workflow.

The tool facilitates researchers to consider:

  • Bathymetry/topography of the ocean floor
  • Shallow-water solutions as boundary conditions
  • User-defined buildings
  • UQ methods like forward propagation, sensitivity and reliability analysis
  • Building models include MDOF, steel building model and OpenSees models

In addition, the tool specifically allows for modeling of experiments from wave flumes (for example, the NHERI Experimental Facility at Oregon State University). The outputs of the HydroUQ include probabilistic building responses, velocities and pressure at any point in the fluid domain.

These simulations are computationally demanding and thus, users have the option to perform the computations on the Frontera supercomputer. Frontera is located at the Texas Advanced Computing Center and made available to the user through NSF's NHERI DesignSafe, the cyberinfrastructure provider for NHERI.
