General Notes

Note: To import Synergi data, you need at least version 4.3 of Synergi (versions 4.3 to 4.7 are supported).

Due to differences between InfoWorks WS and Synergi data models, a number of adjustments are made during the import process:

Synergi node and link names have a length of 32 characters. InfoWorks WS node names are restricted to 30 characters. The importer will truncate names over 30 characters in length.
Synergi labels are not imported.
Synergi scripts are not imported.
Synergi pump types HP and QH are not imported.
Synergi can include assets in the model that are marked as inactive. All elements in the Synergi model are imported into the InfoWorks network. Active elements are saved in a selection list which is included in the InfoWorks run object. Inactive elements are therefore excluded from the run by default.

Run Settings

The settings on the Schedule Hydraulic Run View are set to the following:

Run Schedule	Value

Note that profiles are not imported. IWWS substitutes its own internal profile curve.

Valves on reservoir links are converted to float valves in InfoWorks to prevent reservoir overtopping.

Regulation Type	Continuous if a profile is specified or if the regulating range (see below) is 0. On/Off if no profile.
Opening (%)	Valve Tau is converted to opening.
Regulating range	Imported from Synergi.
Inlet level	Elevation of From Node.
Backfeed pipe	Set to default value by InfoWorks: No for Synergi tank fill valves. Yes for other valves.
Control Depth (control data)	If a valve profile is specified in Synergi: Top water level – first X value in valve profile. (X valves in Synergi specify the drop from the top of the reservoir). If no profile is specified: Top water level – bottom water level
Initially Open (control data)	Open if initial position > 0.5. Closed if initial position <= 0.5.

Nodes

IWWS Data Field	Values imported from Synergi
Node ID	Node Name

Notes	Node Description

Fixed Heads

Nodes are imported as fixed head nodes if they have a known pressure and they are not a control node for a valve or a pumping station. If the fixed head nodes have demand in Synergi then the demands are not imported because fixed head nodes in InfoWorks cannot have demand.

Transfer Nodes

Nodes are imported as transfer nodes if they have negative demand. If the transfer node has more than one demand category only the first category will be imported.
