2.9. UQ: Uncertainty Quantification
The first selection panel the user must select from and enter data into is the UQ tab. It is in this panel that the user selects the UQ Engine to use for performing the uncertainty quantification calculations. The UQ Engine provides algorithms for solving various types of uncertainty analysis and optimization problems.
Presently the only UQ Engine option is Dakota.
2.9.1. Dakota UQ Engine
This UQ engine utilizes the Dakota Software, a state-of-the-art research application that is robust and provides many methods for optimization and UQ, a selection of which we utilize in this application. Dakota provides the user with a large number of methods for different kinds of analyses. For this reason we have divided the methods into categories though a pull-down menu, as shown in Fig. 2.9.1.1. Once the category has been selected, a number of different methods are made available to the user.
