works W S pro allows you to model different scenarios
00:08
which essentially act as different versions of a network or control
00:13
scenarios can be used to model alternate networks and controls including
00:18
the ability to rezone networks or remove parts of the model
00:22
scenarios.
00:23
Also let you track changes to the base network and control so they remain up to date.
00:31
In this example, a new model group has been created,
00:34
the network has a control and a demand diagram already associated with it.
00:39
And a new run group has been named baseline.
00:42
The new run now appears under the run group.
00:45
It is now time to create a new scenario
00:48
in the toolbar, click the create scenario button or in the ribbon
00:53
scenarios. Tab pick create scenario
00:57
in the create new scenario,
00:58
dialogue type pipe replacement in the new scenario name field,
01:03
leave the box next to copy and existing scenario deselected.
01:08
It is recommended that you enable the option,
01:10
create matching scenario in the control as it makes
01:13
a connection between the network and control for you.
01:17
This is convenient when you start creating multiple scenarios as the system
01:21
will automatically know which network and control to use for each one
01:25
click. OK.
01:27
The pipe replacement scenario now appears in the dropdown in the toolbar.
01:32
You can also click the manage scenarios, icon, select network,
01:37
then view the scenarios in the manage network scenarios.
01:40
Dialogue
01:42
in the model group window.
01:44
Notice that under the session zero and four model group,
01:47
the network and control are marked with red circles with exclamation marks.
01:53
Those icons are simply to notify you that you
01:55
have made changes to both the network and control.
01:59
For this scenario, you will replace an existing pipe with a new pipe
02:05
in the toolbar. Click the find network objects tool
02:08
in the match identifier group Boxx insure asset is active,
02:13
check the box next to links
02:15
and enter 193479 asterisk into the wildcard field.
02:22
Then click the asset ID number to highlight it and click select and find
02:28
the pipe is highlighted in red in the GEO plan
02:32
before making any changes. Make sure you are working in the correct scenario.
02:37
The drop down in the toolbar should read pipe replacement
02:40
and make sure you can see both nodes at each end of the pipe
02:46
in the toolbar, expand the object dropdown and select link.
02:51
Then click the new object button,
02:55
then click the node at the lower left end of the pipe.
02:59
Click again somewhere above the pipe to add another link,
03:03
then click the node at the other end of the pipe.
03:07
The create new link dialogue appears
03:10
click. Ok.
03:12
A new pipe bypassing the old one now appears in the
03:15
network and its properties can be viewed in the property's window.
03:19
However, the pipe requires you to specify a diameter in friction coefficient
03:25
type a value of 100 in the diameter field
03:28
and a value of 0.1 in the friction coefficient field
03:34
in the toolbar.
03:35
Click the select tool and then in the GEO plan,
03:38
click the old pipe to highlight it in red.
03:42
Now click the confirmed deletion button.
03:47
A notification appears warning that you are about to delete the selected object.
03:52
Click. Ok.
03:54
The pipe you just deleted now appears in gray because it still exists in
03:59
the base scenario but not in the
04:01
pipe replacement scenario you are currently working on
04:05
in the toolbar,
04:06
expand the scenario dropdown and select base to see the
04:10
old pipe revert to its original dark blue color.
04:14
Switch back to the pipe replacement scenario
04:18
to validate the model in the toolbar. Click the validate button
04:23
in the network validation dialogue in the scenarios group box.
04:27
Ensure only the box next to pipe replacement is checked,
04:31
click. OK.
04:33
In this example, no errors appear in the output window so you can close it.

InfoWorks WS Pro allows you to model different scenarios, which act as different versions of a network or control. Scenarios can be used to model alternate networks and controls, including the ability to rezone networks or remove parts of the model. Scenarios also let you track changes to the base network and control, so they remain up to date.
For this exercise, a new model group and a new run group are already created.
Enabling this option creates a connection between the network and control.
In the Scenarios toolbar, in the Select scenarios drop-down, Pipe Replacement now appears.
To replace an existing pipe with a new pipe:
In the GeoPlan, the found pipe is highlighted in red.
Note: Before making changes, always confirm you are working in the correct scenario. In this example, in the Scenarios toolbar, the Select scenario drop-down should read, “Pipe Replacement”, and in the GeoPlan, both nodes at each of the pipe should be visible.
Notice that a new pipe bypassing the old one now appears in the network.
Notice that the deleted pipe now appears gray, because it still exists in the Base scenario, but not in the current Pipe Replacement scenario.
Notice that the old pipe reverts to its original dark blue color.
To validate the model:
In the Output Window, notice there are no errors.
