Quantified Uncertainty with Optimization for the Finite Element Method (quoFEM) is an open-source research application, that is hosted on the quoFEM Github page, and released under the 2-Clause BSD license (see Copyright and License ). The application provides uncertainty quantification methods (forward, inverse, reliability, sensitivity, parameter estimation, and surrogate modeling) to researchers in natural hazards who utilize existing simulation software applications, such as Finite Element applications, in their research. It has been developed at the SimCenter, within the University of California, Berkeley. The SimCenter is part of the Natural Hazards Engineering Research Infrastructure (NHERI) program, funded by the National Science Foundation.
Depending on the type of numerical simulation being performed, the additional simulation required for uncertainty quantification can be computationally prohibitively expensive. To overcome this impediment, the user has the option to perform the response simulations on the Stampede2 supercomputer. Stampede2 is located at the Texas Advanced Computing Center (TACC) and made available to the user through NHERI DesignSafe-CI, the cyberinfrastructure provider for the distributed NSF-funded Natural Hazards Engineering Research Infrastructure (NHERI) facility.
