10.1 Creating an analysis

New analyses are added within the Analyses card. To add a new one, click on the + Add button. A menu will appear, showing all types of TPA analyses implemented in SOURCE. Depending on the types of data that have been loaded and the types of channels that have been specified in the data, SOURCE will recognize the type of TPA that can be performed and highlight the available analyses.

After selecting your desired analysis, it will appear in the Analyses card. The name of the analysis can be changed by right-clicking and selecting Rename. By default, the analysis will include all of the loaded operational and FRF data; this information is shown below the analysis name.

Defining analysis inputs

As mentioned, the analysis will include all previously selected operational and FRF data by default. To modify this: first select the desired analysis in the Analyses card, and then in the Inputs card select or deselect the desired operational data, FRF data, and channels. For example, the channel selection is showed in the figure below.

Duplicating an analysis

One of the strong features of SOURCE is the ability to perform several analyses on any combination of datasets. By right-clicking on an analysis in the Analyses card and selecting Duplicate, we create a duplicate analysis. We can then change, for example, the matrix inverse settings or the forces used in the TPA, and easily see what effect this has on the results.

Computing results

To compute the analysis, within the Analyses card, you can either:

1. Click on the small calculator on the right of the analysis, or
2. Right-click on the analysis itself and select Compute.

When the analysis is finished, the results will appear in the Results tab of the Inputs/Results card. Switch this card to Results to review the results.
