Creating and assigning a diurnal pattern

00:04

To further prepare for an extended period simulation.

00:07

You can add pattern data.

00:09

A pattern is a graph assigned to an element that is

00:12

used to represent temporal or time dependent variations within the system.

00:17

For example, you can create and assign a diurnal pattern

00:21

and then use it to simulate the variation in demand over the day

00:26

to begin. Double click the desired project dot

00:30

ARX file to open Argi

00:31

pro.

00:33

Once the project starts,

00:34

click the info water pro tab to open the info water pro ribbon

00:39

in the project panel, click initialize

00:44

in the model explorer on the operation tab expand pattern.

00:47

If it is not already expanded,

00:50

you can see that there are several pre configured patterns to choose from.

00:54

However, you can create your own pattern,

00:58

right, click pattern, select new and enter the pattern ID as standard

01:05

click. OK.

01:07

The pattern dialog box appears which enables you to create edit

01:11

clone and delete patterns.

01:15

It shows all existing patterns on the top and the highlighted patterns,

01:18

data in both tabular and graphical format on the bottom

01:23

in the toolbar of the pattern dialog box, click the set rows icon

01:27

and then in the pattern pop up. Enter a value of 24 for the number of pattern factors.

01:33

Click OK.

01:35

The pattern dialogue populates the value table and a graph appears on the right.

01:40

The data you enter here comes from the municipality's water usage data

01:44

gathered from the meters of every building attached to the system.

01:48

As a hydraulic modeler,

01:50

you should have access to the data for the municipality or utility.

01:53

You are modeling for

01:56

the training model in this exercise is actually a real city.

01:59

So the pattern data you enter here will provide real world results.

02:04

Set the value for the 24 rows. As follows.

02:08

You can see the data graph populate with these values.

02:11

Be aware that if you have a very large number of values to enter,

02:15

you can import a CSV file and populate it that way.

02:20

Click OK to commit your changes and close the pattern dialog box.

02:25

Now that you have created your pattern, you need to apply it to the demand

02:29

on the info water pro ribbon

02:31

in the edit panel, click the DB editor,

02:35

select the junction demand modeling data table and then click OK.

02:41

In the DB editor, click the pattern one column heading to select the whole column.

02:46

Then from the toolbar, click the block editing icon

02:49

and in the block edit pop-up set the operation

02:52

to replace with and enter a value of standard.

02:57

This is the pattern that you previously set up,

03:00

click save and then exit to close the DB editor

03:05

now select any junction in the system.

03:08

And in the model explorer attribute tab,

03:11

you can see that the pattern one field is now set to standard.

03:15

If you need to make any changes to the pattern,

03:17

you can open the pattern dialog box by double clicking pattern one.

03:21

In the model explorer.

03:23

The pattern dialogue opens again with the standard pattern active.
