Using themes

00:04

When using info works. WS pro there may be times when you need to use themes.

00:09

Themes are useful when you want to see how a

00:11

group of objects is behaving by color coding them.

00:15

In this example,

00:16

you will perform a rezone in your network and

00:19

then use themes to see how water pressure changes

00:23

with the session. 04 base scenario open in the GEO plan

00:27

in the toolbar. Click the create new scenario button

00:33

in the create new scenario dialogue. Enter the name rezone

00:37

and then click, OK.

00:40

Now find the pipe with the asset ID 144 688.

00:46

You will be closing the pipe to simulate a burst or similar problem.

00:51

Open the pipe's properties and scroll in the window to find the pipe closed row.

00:56

Check the box

00:58

as soon as you do notice that in the GEO plan, A red X appears on the pipe.

01:05

Next find the valve with the asset ID 203 4, 298 and open its properties.

01:12

Find the opening percentage row and type in a value of 100.

01:17

In this situation,

01:18

you might open the valve to reroute water around

01:21

the damaged pipe to avoid interruption to the supply.

01:25

Commit the changes you just made to both the network and control

01:31

next. Create a new run and title it. Rezone

01:37

click and drag the bridge net network into the network group box.

01:41

Make sure the experimental option is enabled

01:46

in the scenarios. Tab enable the base and rezone options as well.

01:51

Click save then run,

01:56

expand the rezone, run and click and drag rezone bridge con into the workspace.

02:03

Then

02:04

right click bridge con select open as

02:07

and in the select results, dialogue, click as alternate results for comparison,

02:12

then click. OK.

02:15

Now you can apply a predefined theme to the model,

02:19

expand the theme group and then expand factory

02:23

a

02:24

click and drag the nodal pressure theme into the run and observe how the

02:28

nodes are now color coded to reflect changes in water pressure across the network.

02:34

You can click through the timeline bar at the top

02:36

of the window to see how pressure changes over time

02:40

to understand what each color represents

02:43

in the toolbar. Click thematic key window

02:48

in the thematic key window,

02:49

expand node and then pressure to reveal a series

02:53

of colors each standing for a different pressure level.

02:57

Locate pipe 144, 688 again

03:03

because the pipe is closed, you can see a drop in pressure in the network downstream.

03:08

And because you open the valve pressure downstream of the closed pipe drops,

03:12

but flow is maintained

03:15

to see individual customer pressure. You can apply an SQL

03:20

in the model group window, expand the stored query group

03:24

and double click compare minimum customer pressure

03:29

deselect the option, apply filter to current selection

03:33

and then run the SQL

03:37

in the results window. The SIM one column represents the rezone run

03:41

and SIM two represents the base run.

03:45

You can see in the difference column, a value of minus 0.69,

03:50

meaning there was only a small drop in pressure.

03:53

This indicates the rezone was at least somewhat successful.

03:59

You can try different SQS if necessary.

04:01

For example, to view notable pressure across the network,

04:05

just remember that if you are running an SQL for a selected group of objects,

04:09

you need to re enable the apply filter to current selection option.

Step-by-step Guide

In InfoWorks WS Pro, themes are useful to see how a group of objects is behaving by color-coding them. For example, if you perform a rezone in a network, themes allow you to see how water pressure changes.

  1. Open the Session 04 Base scenario in the GeoPlan.
  2. In the Scenarios toolbar, click Create new scenario.

The InfoWorks WS Pro toolbar with the Create new scenario command called out and selected.

  1. In the Create New Scenario dialog box, enter the name “Rezone”.
  2. Click OK.

The Create New Scenario dialog box with the options configured.

  1. Use the Find Network Objects command to locate the pipe with the asset ID 144688.

In the Network Find dialog box, options configured to find a pipe using its asset ID, and Select and find selected.

To close the pipe, simulating a burst or similar problem:

  1. In the Tools toolbar, select Properties.

The Tools toolbar with the Properties command selected.

  1. In the Properties window, under Pipe Closed Profile, enable Pipe Closed.

The Properties window with the Pipe Closed enabled.

Note in the GeoPlan, a red “X” appears on the pipe.

In the GeoPlan, the closed pipe highlighted in red and marked with a red “X”.

  1. Find the valve with the asset ID 234298.
  2. Select Properties.
  3. In the Properties window, under Valve Control, set the Opening (%) to “100”.

The Properties window for the selected valve, with the Opening (%) field set to “100”.

Note: In this situation, you might open the valve to reroute water around the damaged pipe to avoid interruption to the supply.

  1. Commit the changes to both the network and the control.
  2. From the Model Group window, right-click Run Group and select New > Run.

The Run Group shortcut menu.

  1. In the Schedule Hydraulic Run dialog box, title the run “Rezone”.
  2. Drag-and-drop the BridgeNet network into the Network group box.
  3. Enable Experimental.

The Schedule Hydraulic Run dialog box with options configured for the Rezone run.

  1. In the Scenarios tab, enable Base.
  2. Enable Rezone.
  3. Click Save.
  4. Click Run.

The Schedule Hydraulic Run dialog box, with Base and Rezone selected in the Scenarios tab and Save selected.

  1. In the Model Group window, expand Rezone. Drag-and-drop [Rezone] BridgeCon into the workspace.
  2. Right-click BridgeCon and select Open as.

The Model Group window, Rezone Control shortcut menu with Open as selected and called out, and the GeoPlan with the Rezone run open.

  1. In the Select Results dialog box, click As Alternate Results For Comparison.
  2. Click OK.

The Select Results dialog box.

To apply a predefined theme to the model:

  1. In the Model Group window, expand Theme Group.
  2. Expand Factory (add).
  3. Drag-and-drop the Nodal Pressure theme into the run GeoPlan.

Notice the nodes are color-coded to reflect changes in water pressure across the network.

The Model Group window file tree, with Theme Group and Factory (add) expanded to show predefined themes; and the GeoPlan with the Nodal Pressure theme applied.

  1. Click through the timeline bar in the top-left corner of the GeoPlan to see how pressure changes over time.

To understand what each color represents:

  1. In the toolbar, click Thematic key window.

The Docking windows toolbar with the Thematic key window command called out.

  1. In the Thematic Key Window, expand Node and pressure to review the color key relating to water pressure.

The Thematic Key window, with Node and pressure expanded to reveal the color key related to water pressure.

  1. Locate pipe 144688 again.

Notice that with the pipe closed, the drop in pressure in the network is downstream, but with the valve open, flow is maintained.

To apply an SQL to review individual customer pressure:

  1. In the Model Group window, expand Stored Query Group.
  2. Double-click Compare Minimum Customer Pressure.

The Model Group window file tree expanded with Compare Minimum Customer Pressure selected.

  1. In the SQL dialog box, deselect Apply Filter To Current Selection.
  2. Click Run.

The SQL dialog box with Apply Filter To Current Selection deselected and Run selected.

In the results window, Sim 1 represents the Rezone run, and Sim 2 represents the Base run. The Difference of –0.69 indicates only a small drop in pressure. Therefore, the rezone was somewhat successful.

The Results window comparing minimum customer pressure for the Rezone and the Base run.
