The Quantified Uncertainty with Optimization for the Finite Element Method (quoFEM) application is designed to advance the integration of uncertainty quantification and optimization in the field of natural hazards engineering. This application accomplishes this goal by integrating established finite element applications such as OpenSees and FEAPpv with uncertainty quantification tools like Dakota through a user-friendly interface. By combining tools like these, quoFEM enhances finite element applications with robust uncertainty quantification and optimization functionalities.
To address the challenge of computational overhead that can burden the execution of probabilistic analyses, users have the flexibility to specify that simulations be conducted on high-performance computing (HPC) resources. For instance, users can run simulations on the Frontera supercomputer at TACC, which is accessible through our NHERI partner, DesignSafe.
The quoFEM application offers a range of analytical capabilities, including:
