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.
