Performing a generalized pipe break assessment

00:03

This example is going to work through the configuration and simulation of a GMR.

00:08

For a pipe brake assessment.

00:10

You will configure the GMR to break each pipe

00:13

one by one and run a simulation for each bra

00:17

to begin open a network and control in the background.

00:22

Then in the model group window, right,

00:24

click generalized multi run group and select new generalized multi run config

00:31

a new name dialogue displays

00:33

for this example, set the name to pipe break assessment and then click OK.

00:40

A new generalized multi run appears in the model group window,

00:43

right? Click pipe brake assessment and select open

00:47

within the generalized multi run configuration dialogue.

00:50

Navigate to the test cases tab

00:53

from the model group dragon drop the pipes selection list into the selection list,

00:57

pane

00:58

expand the object type dropdown and choose pipe control.

01:04

Then in the grid scroll down to brake enabled and turn this on.

01:10

Then set the break start time to eight o'clock

01:14

and the break end time to nine o'clock.

01:17

Lastly set the brake type to rupture

01:22

in the test case name field. Enter a name to be used for all test cases,

01:27

insert pipe in the test case name and then enable the append

01:31

object ID to test case name. Option.

01:34

Click add to populate the table with test cases.

01:38

Next, click the results tab,

01:41

select keep all TVD results and individual summaries,

01:45

click the analysis tab and select use stored query

01:51

from the model group.

01:52

Expand the stored query group and drag the CP

01:55

less than 20 m SQL into the stored query pane

01:59

set the query time to be 25 2022 at nine o'clock

02:05

from the model group, right, click run group and select new

02:09

run

02:11

name this run pipe brake assessment in the schedule,

02:14

hydraulic run dialogue and then set the run to experimental

02:19

in the schedule. Hydraulic run dialogue.

02:21

Ensure a network control and demand diagram are assigned,

02:26

expand the run type dropdown and select normal.

02:31

Then from the run type group, select generalized multi run

02:37

from the generalized multi run options.

02:39

Dialogue specify the previously created pipe

02:42

break assessment configuration by dragging it

02:44

from the model group and dropping it into the configuration pane.

02:48

Or you could select browse navigate to the configuration you want

02:53

and select it.

02:55

Click ok

02:57

back in the schedule. Hydraulic run dialogue, click run

03:02

after a few minutes. The run displays in the model group window,

03:07

you will notice a number of simulations are present as well as the summary report.

03:14

The simulations are those that have met the criteria specified in the stored query.

03:19

Right? Click the control simulation

03:22

and select open as

03:24

summary report,

03:26

a summary report appears that includes a summary of each

03:29

test case where the maximum pressure is below 20 m.

03:33

It also includes columns for the minimum average and maximum

03:37

pressures as well as the id of the customer point.

03:40

It occurs at

03:41

this data represents the constraints you applied through

03:44

the CP less than 20 m stored query.

03:48

Right click one of the test case simulations

03:51

from here, you can open this as a summary that is specific to that simulation

03:56

or you can open it as simulation results on the

03:59

GEO plan and apply any themes or labeling necessary.
