Building Subnetwork

AmberY

Hello,

I am in the midst of building subnetwork for water network and having some doubts on this and hoping this communities can share some thoughts on this.

In the supply tier with supply as a controller (refer to pic attached), I want to build the subnetwork for supply-1 and supply-2 and the subnetwork will stops when it meets the closed valve or reach the end of pipeline.

Given that Area C receives water from both Supply-1 and Supply-2, but in a hierarchical network, a feature can't belong to more than one subnetwork in the same tier, how can I model the subnetwork so that when I run a subnetwork controller trace, it returns both Supply-1 and Supply-2 for Area C, but only Supply-2 for Area D? We didn't combine both supplies into one subnetwork to avoid misleading results, as only Area C gets water from both, while other areas do not. Combining them would suggest that all areas receive water from both supplies i suppose.

Thanks in advanced!

If all the water supplies are mixed than they should all be a single water system subnetwork. Each subnetwork controller has its own unique name, as well as the name of the subnetwork it controls.

Supply 1 would have a subnetwork controller name of "Supply 1" and a subnetwork name of "System A".

Supply 2 would have a subnetwork controller name of "Supply 2" and a subnetwork name of "System A".

When you run an upstream trace from inside Area A, it will show a path to Supply 1. When you run an upstream trace from inside Area D it will show a path to Supply 2. When you run an upstream trace inside Area C it will show you paths to Supply 1 and Supply 2.
