Flows Without a Valid Source and/or Destination

This analysis rule includes the flow elements with no connections on their source, destination, or both. When flows are used to represent the movement of material from a source to destination, any flow that is not connected on both ends is suspect. The failure of this test often indicates a modeling error or a missing element.

Any flow missing a source or destination Element is reported to the Case log which you can view in the Log tab of the Case Properties window. The analysis rule name, the Model name and the time this analysis rule was run are also written at the top of the report.

The following table lists a sample log output for this analysis.

Analysis Method​

  1. Collect a list of all flow elements in the current Case that satisfy the following criteria:
  • Status Attribute value is IS (In Service)
  1. For each flow, determine the connectivity. If a flow has no source, no destination, or both, it has failed this test.
  2. Write to the log section of the case. Report the violating flow connection information.

Configuration Using the Wizard​

The configuration of the Flows without Valid Source / Destination is a selection of the General Gross Error Analysis Rule. You open the window for configuring the test (shown in the following figure) from the General Gross Error Analysis Rule Wizard.

  1. Open the Gross Error Configuration window as described in Configuring - General Gross Error Analysis Rule.

  2. On the Flows tab, select Flows without valid source / destination.

    A Flows without valid source / destination - Attributes window opens.Figure 402: Flows without valid source / destination - Attributes window

  3. Select the Attribute for In-Service Status. The following table provides a description.

    Attributes

    SelectionsDescription
    StatusFlow in/out of service status. The default is 'ObjectStatus'.

  4. Click OK to finish the configuration.

    The text "CONFIGURED" displays next to the 'Flows without valid source and destination' selection.

  5. To run this test, see Running the General Gross Error Analysis.
