When running a flushing analysis, the following user notification is generated:
"Reference to a deleted or inactive element of interest."
This issue is occurring because one or more pipe (or one or more node) is included in the flushing event is either inactive or has been deleted from the model. To resolve this, open the Flushing manager under Analysis > Flushing. Selected the flushing area that is affected and go to the Options tab. Then selected the ellipsis ("...") button next to the Pipe Set collection field.
After selecting the ellipsis button, if there are pipes that are in the collection have are no longer in the model, you will receive a message indicating this. Clicking Okay will remove the pipes.
Click the ellipsis button next to the Nodes of Interest collection and see if you get a similar message, stating that one node in the collection has been deleted. Clicking Okay will remove the node.
When this is done, the collection for the Pipe Set and Nodes of Interest should be updated and accurate. Try rerunning the flushing analysis and the issue should no longer occur.
