Quantified Uncertainty with Optimization for the Finite Element Method (quoFEM) Application

This application (formerly uqFEM) is intended to advance the use of uncertainty quantification and optimization within the field natural hazards engineering. The application achieves this by combining existing finite element applications, e.g. FEAPpv, with uncertainty quantification (UQ) applications, e.g. Dakota, behind a simple user interface (UI).

WE-UQ Application

This is an open-source software that provides researchers a tool to assess the performance of a building to wind loading. The application is focused on quantifying the uncertainties in the predicted response, given that the properties of the building and the wind loads are not known exactly, and given that the simulation software and the user make simplifying assumptions in the numerical modeling of the structure.

V2.0 Sep 2019



This application assess the performance of a building subjected to water loading during tsunami and storm surge events. The tool allows 2-D shallow water solutions obtained from far-from-coast calculations as boundary condition input to a 3-D CFD solver. This multiscale coupling facilitates the resolving of regions of interest.
