Describe the different types of ancillary links in InfoWorks ICM.
In InfoWorks ICM, an ancillary control object, such as a weir or a pump, represents a flow control structure. Ancillary controls are assumed to have zero length, and like a conduit, the ancillary control is defined as a link between two nodes. When working with Real Time Control, the state of ancillary regulator structures are set up to change according to the state of sensors elsewhere in the network.
The different types of ancillary controls have different data requirements.
All other controls are treated as hydraulically identical for both directions of flow.
Some of the ancillaries available in InfoWorks ICM include:
Ancillary data can be edited in either the respective Grid View of the Links Grid or the Object Property Sheet. However, to view and edit all ancillary link data, use the Grid View. Many of the ancillary control equations and parameters are based on British standards. For detailed explanations of the equations used for the different types of ancillary links, refer to InfoWorks ICM Online Help.
