Overview

The Network Navigator consists of a toolbar and a table that lists the Label and ID of each of the elements contained within the current selection. Predefined queries can help you select certain queries with an ease without spending too much time.   

To open the Network Navigator, click the View menu and select the Network Navigator command, press , or click the Network Navigator button on the View toolbar.

Physical Overview of Network Navigator

Predefined Queries

The Network Navigator provides access to a number of predefined queries grouped categorically, accessed by clicking the [>] button. Categories and the queries contained therein include

Network

Network queries include "All Elements" queries for each element type, allowing you to display all elements of any type in the Network Navigator. 

Network Review 

Network Review Queries include the following:

Nodes In Close Proximity - Identifies nodes within a specific tolerance.
Crossing Pipes - Identifies pipes that intersect one another with no junction at the intersection.
Orphaned Nodes - Identifies nodes that are not connected to a pipe in the model.
Orphaned Isolation Valves - Identifies isolation valves that are not connected to a pipe in the model.
Dead End Nodes - Identifies nodes that are only connected to one pipe.
Dead End Junctions - Identifies junctions that are only connected to one pipe.
Pipe Split Candidates- Identifies nodes near a pipe that may be intended to be nodes along the pipe. The tolerance value can be set for the maximum distance from the pipe where the node should be considered as a pipe split candidate.
Pipes Missing Nodes - Identifies which pipes are missing either one or both end nodes.
Duplicate Pipes - Identifies instances in the model where a pipe shares both end nodes with another pipe.

Network Trace

Network Trace Queries include the following:

Find Connected - Locates all the connected elements to the selected element in the network.
Find Adjacent Nodes - Locates all node elements connected upstream or downstream of the selected element or elements.
Find Adjacent Links - Locates all link elements connected upstream or downstream of the selected element or elements.
Find Disconnected - Locates all the disconnected elements in the network by reporting all the elements not connected to the selected element.
Find Shortest Path - Select a Start Node and a Stop Node. The query reports the shortest path between the two nodes based upon the shortest number of edges.
Trace Upstream - Locates all the elements connected upstream of the selected downstream element.
Trace Downstream - Locates all the elements connected downstream of the selected upstream element.
Isolate - Select an element that needs to be serviced. Run the query to locate the nearest isolation valves. In order to service the element, this will identify where shut off points and isolation valves are located.
Find Initially Isolated Elements - Locates elements that are not connected or cannot be reached from any boundary condition.

Input

Input Queries include a number of queries that allow you to find elements that satisfy various conditions based on input data specified for them. Input queries include:

Duplicate Labels - Locates duplicate labels according to parameters set by the user. See Using the Duplicate Labels Query for more information.
Elements With SCADA Data - Locates elements that are have SCADA data associated with them.
Inactive Elements - Locates elements that have been set to Inactive.
Pipes with Check Valves - Locates pipes that have the Has Check Valve? input attribute set to True.
Controlled Elements - Locates all elements that are referenced in a control Action.
Controlled Pumps - Locates all pumps that are referenced in a control Action.
Controlled Valves - Locates all valves that are referenced in a control Action.
Controlled Pipes - Locates all pipes that are referenced in a control Action.
Controlling Elements - Locates all elements that are referenced in a control Condition.
Initially Off Pumps - Locates all pumps whose Status (Initial) input attribute is set to Off.
Initially Closed Control Valves - Locates all control valves whose Status (Initial) input attribute is set to Closed.
Initially Inactive Control Valves - Locates all control valves whose Status (Initial) input attribute is set to Inactive.
Initially Closed Pipes - Locates all pipes whose Status (Initial) input attribute is set to Closed.
Fire Flow Nodes - Locates nodes included in the group of elements specified in the Fire Flow Alternative's Fire Flow Nodes field.
Constituent Source Nodes - Locates all nodes whose Is Constituent Source? input attribute is set to True.
Nodes with Non-Zero Initial Constituent Concentration - Locates all nodes whose Concentration (Initial) input attribute value is something other than zero.
Tanks with Local Bulk Reaction Rate Coefficient - Locates all tanks whose Specify Local Bulk Rate? input attribute is set to True.
Pipes with Local Reaction Rate Coefficients - Locates all pipes whose Specify Local Bulk Reaction Rate? input attribute is set to True.
Pipes with Hyperlinks - Locates all pipes that have one or more associated hyperlinks.
Nodes with Hyperlinks - Locates all nodes that have one or more associated hyperlinks.

Results

Results Queries include a number of queries that allow you to find elements that satisfy various conditions based on output results calculated for them. Results queries include:

Negative Pressures - Locates all nodes that have negative calculated pressure results.
Pumps Operating Out of Range - Locates all pumps whose Pump Exceeds Operating Range? result attribute displays True.
Pumps Cannot Deliver Flow or Head - Locates all pumps whose Cannot Deliver Flow or Head? result attribute displays True.
Valves Cannot Deliver Flow or Head - Locates all valves whose Cannot Deliver Flow or Head? result attribute displays True.
Empty Tanks - Locates all tanks whose Status (Calculated) result attribute displays Empty.
Full Tanks - Locates all tanks whose Status (Calculated) result attribute displays Full.
Off Pumps - Locates all pumps whose Status (Calculated) result attribute displays Off.
Closed Control Valves - Locates all control valves whose Status (Calculated) result attribute displays Closed.
Inactive Control Valves - Locates all control valves whose Status (Calculated) result attribute displays Inactive.
Closed Pipes - Locates all pipes whose Status (Calculated) result attribute displays Closed.
Failed Fire Flow Constraints - Locates all elements whose Satisfies Fire Flow Constraints? result attribute displays False.
