Im running a fire flow analysis and the model appears to run fine but it does give me a status message that my reservoir is closed. Is this something that I need to address? I am using a reservoir and pump to model a known hydrant flow & pressure from the city.
Is the pump status off or are there closed pipes near the reservoir? If so this might account for the user notification. I would take a look at the results, particularly around the reservoir. See if you have no flow reported. Also see if there are any red user notifications that might need to be addressed. Any red user notification tends to mean that the model did not compute.
The following links may help with some issues that may arise:
Disconnected Demand Nodes user notification when computing model
Troubleshooting the Network Unbalanced or Cannot solve network hydraulic equations user notification
If that doesn't help, we may need to see a copy of the model files. This link has information on sending the files to us.
Its been awhile since I have used this program and I am running into the same problem. I have been unable to find any disconnected nodes. My model is only running 2 nodes and I get the message Reservoir R-8 closed if I exclude non fire flow demand and I get Reservoir R-8 is emptying if I add constant demand. Attached here is the file I am using. Would you be able to help me out with what I am doing wrong here?

Only the .wtg file was included. Please sent the .wtg.sqlite file to us to. Then will be able to open the model file.
Westin WaterCAD.zip Let me know if this works. I don't see a .SQLite file, but included the .wtg, .mdb, .bak & .dwh
When I compute the model in the latest version of WaterCAD, I get a message that says Network Unbalanced. The issue is occurring because there are no demands in the model during the steady state. This cannot sometimes cause the model calculation to be difficult to solve the network hydraulic equations. This link has information on that.
To get this to compute, I added a 5 gpm of flow to a node in the system, and was able to get this to balance. Please try that on your computer and see if it helps.
