Nodes missing from or listed multiple times in the Demand Control Center

Problem

In the Demand Control Center, some of the junctions are listed multiple times. Or, certain junctions are not appearing at all in the Demand Control Center (and the count of rows in the Demand Control Center is less than the number of junctions seen in the junction flextable).

Solution

This occurs when the junction has more than one demand applied. For instance, suppose that a junction is listed three times. If you view the Demand Collection section in the junction Properties dialog box, there will be three listings.

In other words, a node can have a composite demand where the total demand is made up of multiple individual demands, such as from different sources that are lumped together into the single node element.

Conversely, if you do not have any demand added to a junction, that junction will not appear at all in the Demand Control Center, since it only shows junctions with demands.
