Working with demand area live data usage

Step-by-step Guide

In InfoWorks WS Pro, a demand area analysis provides data that allows users to review the current demand for water and project future potential demand areas.

To view the linked live data for a specific demand area:

1. Open the Demand Area Grid.
2. Right-click Demand Area 35 and select Properties.

3. In the properties dialog box, open the Live Data Usage tab.

The Live Data Usage grid shows:

• The Live Data ID
• The network object to which the Live Data is linked
• The type of Live Data
• How the Live Data is used in the demand calculation

Note: The grid is only populated when the relevant live data configuration file is open, along with the network and control.

Live data Usage may be automatically set to one of several options:

• Inflow specifies flow through the link into the Demand Area only, and its calculation assumes that the connectivity of the bounding links is in the positive direction of flow.
• Outflow specifies flow through the link out of the Demand Area only, and again, its calculation assumes a positive direction of flow.
• AZNP specifies live data used to calculate the Average Zone Night Pressure.
• TP specifies pressure live data assigned to a Target Point.
• Unused specifies live data not used in demand area analysis.
• Flow specifies that the flow through the link is bi-directional. Again, the calculation assumes that the connectivity of the bounding links is in the positive direction of flow.
