Graphing alternate simulation results is useful
00:07
when planning developing and managing water systems
00:11
comparing different simulation results provides visibility into water supply
00:15
network alternatives and water use for future planning.
00:20
In this example, you will create two simulations,
00:23
one of a base scenario and one of
00:25
a scenario that represents a new housing development.
00:30
To create these two simulations, you must first create a new run
00:35
with a run. You can process one or more simulations at once
00:39
before starting. Be sure to copy session five dot WPT into your database.
00:45
Open the bridge net GEO plan and work
00:48
within a new scenario named housing development.
00:52
This new scenario will need a new node
00:54
with allocated demand linked to the existing network.
00:57
Before creating a run a run group needs to be created
01:02
from the model group window, right? Click session 05.
01:05
And from the shortcut menu, select new
01:08
run group
01:10
in the run group dialogue, click OK.
01:14
The run group displays in the model group window
01:17
now it is time to create the run
01:21
from the model group window, right, click run group and from the shortcut menu,
01:25
select new
01:26
run
01:29
the schedule, hydraulic run dialogue displays
01:33
in the title field, enter a descriptive name such as housing development
01:39
to ensure that the simulation can be rerun with the same run title.
01:43
Even if parameters change select experimental
01:47
next, assign the network to the run
01:50
to do this from the model group window drag the
01:53
network named bridge net and drop it in the schedule,
01:56
hydraulic run dialogue network section.
01:60
Once the network is assigned both the
02:02
control and demand diagrams automatically populate.
02:06
next open the scenarios tab
02:09
select both the base scenario and the new housing development scenario.
02:14
Click save and then click run
02:18
a warning dialogue displays indicating that the run will
02:21
perform two simulations which may take a long time.
02:24
Click yes to continue.
02:29
After the run is complete in the model group window under run group.
02:33
The two simulations display
02:35
open the base simulation by dragging the run
02:38
titled bridge con and dropping it into the window
02:43
back in the model group window under run group, right.
02:46
Click the run titled housing development bridge con
02:49
and from the shortcut menu. Select open as
02:54
the select results dialog displays,
02:56
click as alternate results for comparison
02:59
and then click. OK.
03:01
Now you can graph the results of
03:03
a specific network object to compare the simulations
03:07
from the open simulation.
03:09
Locate the preexisting pipe that has a newly created node linked to it.
03:14
It can be helpful to use the find network objects command to locate the pipe easily.
03:21
Once you have located it from the toolbar select graph and select a node of the pipe.
03:27
The select what graph dialogue displays
03:31
from the list of options. Click pressure,
03:33
then select graph alternate results.
03:37
Click OK.
03:39
A graph appears indicating a pressure drop due to
03:42
the demand allocated to the new development network.
03:46
While the pressure level depends upon individual circumstances,
03:50
you can use the comparison of results to
03:52
determine if changes are needed within the network.
03:56
By creating runs to compare simulation results.
03:59
You can easily develop an unlimited number of what if scenarios of
04:03
your network or control without affecting the integrity of the base model.

Graphing alternate simulation results is useful when planning, developing, and managing water systems. Comparing different simulation results provides visibility into water supply network alternatives and water use for future planning. In this example, you will create two simulations—one of a base scenario and one of a scenario that represents a new housing development.
To create the two simulations, first, create a new run:
Note: Selecting Experimental ensures that the simulation can be re-run with the same run title, even if parameters change.
Notice the Control and Demand Diagram automatically populate.
In the Model Group window, under Run Group, the two simulations appear once the run is complete.
To open the simulations:
To graph the results of a specific network object to compare the simulations, first, find the existing pipe with a newly created node linked to it:
Now, to create the graph:
A graph appears, indicating a pressure drop due to the demand allocated to the new development network. Use the results to determine if changes are needed within the network.
Creating more runs to compare simulation results develops unlimited what-if scenarios of your network or control without affecting the integrity of the base model.
