NHERI

Studying coastal hazards with Hydro-UQ

July 28-29, 2021 | 9:00am - 3:00pm PT


Abstract

The NHERI SimCenter is hosting a remote training event to help researchers and students in the area of coastal hazards and focusing on tsunami and storm-surge simulations. The training aims to help researchers and students investigate the structural response due to wave loading during such hazard events.

The training will utilize the SimCenter’s HydroUQ (Water-borne Natural Hazards with Uncertainty Quantification) application. The application combines existing shallow-water & CFD applications, e.g., GeoClaw and OpenFOAM, with UQ applications, e.g., Dakota, behind a simple user interface. The training will highlight features recently delivered in the new HydroUQ application, including uncertainty analysis for structural response due to wave loading on structures.

Day 1 will cover the coupling of 2-D shallow-water with 3-D CFD, and Day 2 will introduce a wave flume digital twin. Attendees will learn how to perform probabilistic analysis using HPC resources at the TACC Stampede2 supercomputer made available through DesignSafe. The training will be an interactive session and include demonstration of capabilities followed by interactively working on example problems.

The two-day online training is being offered on July 28-29, 2021. The training will be followed by open-office hours on July 30, 2021.

  • Day 1: Introduction to new features and capabilities; Using GeoClaw for shallow-water simulations and coupling with CFD using HydroUQ
  • Day 2: Using the wave flume digital twin in HydroUQ; Advanced structural modeling and uncertainty quantification

About the Speaker

Dr. Ajay Harish is a postdoctoral scholar at UC Berkeley and developer at the SimCenter since Jan-2020. He was also a Lecturer at UC Berkeley during Fall 2020. He is the lead developer of the HydroUQ application aimed at Coastal Hazards, particularly tsunami and storm surges. Dr. Harish received his Doctorate (Magna cum laude), in mechanical engineering from Leibniz University Hannover, Germany; M.S. in aeronautics from California Institute of Technology, Pasadena; and B. Tech in mechanical engineering from National Institute of Technology, Surathkal, India. He finds the work at the SimCenter exciting as it is multidisciplinary and combines ideas from engineering, mathematics and computer science.
