Scenario results

Each scenario run creates a distinct result set. Each result set is represented by a tab in the Recording Manager. The name of each tab is formed by concatenating the name of the scenario with a time-stamp indicating when the scenario was run. For example, Figure 1 shows that "Scenario 1" has been run twice at different times.

Figure 1. Recording Manager

You can use the tools on the Recording Manager toolbar to save a result set to a file, export results to Microsoft Excel, or delete the currently-selected result set.

Within each of the Recording Manager’s tabs, results are arranged in four columns:

  • Type - Source generic name for node or link (eg Inflow);
  • Name - your name for that component;
  • Attribute - the name of the output parameter as listed in Parameters (eg. Additional Inflow); and
  • Values - a link which can be clicked to view a graphical representation of the output parameter.

You can navigate through a list of results using the vertical scroll bar. In addition, clicking on a link or node in the Schematic Editor, Geographic Editor or Project Hierarchy automatically selects all of the result sets associated with that component in the Recording Manager.

Right clicking in the Recording Manager, then choosing Save Selected allows you to export the selected time series data as a .csv file. Choosing View Selected opens the Charting Tool for the selected time series data.

One of the key uses of the Recording Manager is to select one or more result sets (rows in the Recording Manager) for display in the Charting Tool. The Charting Tool helps you visualise, analyse and understand scenario results and other data produced by Source. Each time you click a link in the Values column, a copy of the Charting Tool opens to display that result set. Clicking the same link multiple times opens additional copies of the Charting Tool containing the same result set.

Identifying constraints

When constraints are enforced, there may be a difference between the amount of water ordered and that released. The application of constraints is evident at both the supply point and minimum flow requirement nodes.

To discover where constraints have been applied:

  • Run the model;
  • Select an appropriate supply point or minimum flow requirement node. This selects all of the node’s recording parameters in the Recording Manager; and
  • Inspect the Values column in the Recording Manager and click an Order Details link. This opens a Complex Time Series Form (Figure 12). The Graph tab provides a summary of the differences between the amount ordered and the amount released for the duration of the run. The Constraints column of the Table tab (Figure 13) provides a breakdown per time-step. Hover your mouse cursor over a cell of interest to see its contents presented in a tool tip.
