[Gusnet] Positive flow in closed pipe

[hydroTest672]

Hi,
bug is related to closed pipes. When running a simulation, a closed pipe acts like an open one, flow is > 0.

Steps to reproduce the behavior:

1. Create test project with a reservoir (ex 20m)
2. Create a node with demand (ex 5 m3/h)
3. Create a pipe in between with a Closed initial status
4. Run the simulation. Flow and velocity in the pipe are > 0

I am starting to learn about Epanet and Gusnet, but I would expect a zero flow as the pipe is closed?

• Plugin: [3.1.1]
• QGIS: 3.40.6-Bratislava
• Python: 3.12.10
• OS: Windows 11 25H2

Thanks a lot for your help!
