Compare Outputs is a feature currently available for Uncertainty Quantification, Data Analysis and Statistical Optimization methods. Its purpose is to analyze two outputs of the same problem together in order to get an easier interpretation of results and discover new insights.

To do that it is necessary to have two models with the same inputs (designed in the Input Preprocessor).

How to use the interface

For accessing the compare outputs feature, it needs to be selected directly from one output model (similarly to all the other features, from a .upst file). Once it is selected, a pop-up window to select the second output will appear as can be seen in Figure 1.

The following information is displayed for each output:

• File : Allows to select a .upst file, which has all the information from the model relevant to the specific output.
• Method : Shows which method has been used to generate the selected .upst file. This information is shown automatically when the file is loaded. It is important to note that the method of both files has to be the same in order to proceed.
• Output name : Allows to choose the naming given to the outputs for easier interpretation later. By default, it has the same name as the file selected.

By default, all the information required for Output 1, is already pre-established as is taken from the original .upst file.
