An InfoWorks WS Pro network does not have to be fully connected to carry out simulations.
00:09
A network may contain two or more disconnected sections.
00:14
Although you would normally model just one complete network,
00:17
you can model a disconnected network,
00:20
as long as each section of the network contains a way of calculating head.
00:24
A disconnected network is a model that contains more than one unlinked network segment.
00:29
This means that each section must contain a Reservoir, Fixed Head Node, or Well.
00:36
In the Model Group window, expand the Disconnected Model model group.
00:41
Click and drag the Disconnected network to open the network, control, and demand diagram into the workspace.
00:49
Validate the model by clicking Validate in the toolbar.
00:53
The Network Validation dialog opens.
00:56
In this exercise, you can see the network and its associated control in their respective group boxes.
01:03
If the control and demand diagram are not associated, you will need to drag and drop them into their respective boxes.
01:10
Click OK.
01:12
In the Output Window, a warning is presented regarding the Network not being interconnected
01:17
and suggesting the user checks the connectivity..
01:20
The validation presents as a warning rather than an error because both networks have a Fixed Head,
01:25
which indicates that they have been built as two standalone networks,
01:29
rather than one network with missing links.
01:32
To check the connectivity, navigate to the Geoplan ribbon, select Tracing tools and from the fly-out choose Connectivity Trace…
01:41
Here you will see that this model has two separate networks.
01:46
Double click in the margin of row 1.
01:49
The extents of this section of the network will be selected in the Geoplan.
01:53
You can navigate to the upper point of this section and see that the inflow to this section is a transfer node,
01:59
which allows the model to be run as two separate systems.
02:02
Close the Connectivity Trace window.
02:05
To carry out a simulation with disconnected networks, first create a new run group.
02:10
Right-click the Run Group, then select New > Run.
02:15
The Schedule Hydraulic Run dialog opens.
02:18
Type “Disconnected” as the name for the run.
02:21
Check the box next to Experimental.
02:24
Then, under the Run Type, ensure that Normal is selected from the drop-down.
02:29
Next, click the Disconnected System option to enable it.
02:33
If you do not enable the disconnected system option, the run will fail and you will see a red “X” next to the simulation in the model tree.
02:42
Then, in the Model Group window, drag and drop the Disconnected Network into the Network group box
02:47
in the dialog to populate the Network, Control, and Demand Diagram dialogs.
02:53
Click Save and then Run.
02:55
Once the simulation is complete, open the results by dragging and dropping the Control simulation onto the Geoplan.
03:03
After the results open, drag and drop the Flow Direction theme onto the GeoPlan.
03:09
Using this theme, you can see that water moves through the two systems independently.

Required for course completion
An InfoWorks WS Pro network does not have to be fully connected to carry out simulations, and therefore may contain two or more disconnected sections.
Although just one complete network would normally be modelled, a disconnected network may be modelled, as long as each section of the network contains a way of calculating head.
A disconnected network is a model that contains more than one unlinked network segment. This means that each section must contain a Reservoir, Fixed Head Node, or Well.
Note: The Network Validation dialog opens. In this exercise, the network and its associated control are in their respective group boxes.
IMORTANT: In the Output Window, a warning is presented regarding the Network not being interconnected and suggesting the user checks the connectivity. The validation presents as a warning rather than an error, because both networks have a Fixed Head, which indicates that they have been built as two standalone networks, rather than one network with missing links.
To check the connectivity:
Note: This model has two separate networks.
The extents of this section of the network are selected in the GeoPlan:
The inflow to this section is a transfer node, which allows the model to be run as two separate systems:
To carry out a simulation with disconnected networks:
Note: If the Disconnected System option is not enabled, the run will fail, and a red “X” will appear next to the simulation in the model tree.
After the simulation is complete, to open the results:
Note: Using this theme, the water can be observed as moving through the two systems independently.
