Upstream / downstream tracing
The Upstream Trace and Downstream Trace tools can be used on a GeoPlan Window displaying simulation results to analyse direction of flow through the network.
The trace selects all objects in the upstream / downstream direction of flow from a selected link at the currently displayed simulation time.
To carry out a trace:
- Open simulation results in a GeoPlan Window
- Click the
(for upstream trace)
or the 
(for downstream trace) button on the Tools
Toolbar, or select Downstream Trace Mode
/ Upstream Trace Mode from the Tools
menu. - Click any link in the GeoPlan Window
The tool will trace all routes in the upstream / downstream direction of flow from the selected starting link. The trace will stop at:
- Links with flow < 0.01 l/s
- Links with flow in the wrong direction
- Reservoir, Well, Fixed Head and Transfer nodes
