Link Status Results
The Status results attribute is output in the simulation results for Links when the Timestep Log option on the Run Diagnostics Dialog is turned on.
The Status value is provided as additional information to aid diagnosis of problems in simulations. The value output depends on the type of link.
Conduits
Conduit Status is determined by
Upstream End Status + (16 x Downstream End Status)
Where the meaning of end status values is as follows:
|
End Status |
Boundary condition between conduit end and adjoining node |
|---|---|
|
0 |
Headloss |
|
1 |
Free discharge |
|
2 |
Free discharge (full pipe) |
|
3 |
Reset |
|
4 |
Jet |
|
5 |
Free discharge, normal flow |
|
6 |
Free discharge (full pipe), normal flow |
| 7 | FHWA inflow pipe (not plunging) |
| 8 | FHWA outlet control |
| 9 | FHWA submerged inlet control |
| 10 | FHWA unsubmerged inlet control |
Controls
The Status value of Ancillaries is determined by summing the values that are set as described in the table below:

Where the settings are as follows:
Active - set if the control is active
Rev - set if flow < 0
Run-up - set if the pump is running up
Int - set if the pump is in pending off state
F/D - unset if control is free discharge, set if control is drowned
F/S - unset if culvert inlet is free, set if culvert inlet is submerged
O/W - unset if control is using orifice equation, set if control is using weir flow equations
I/O - unset if the culvert inlet is using inlet control, set if the culvert inlet is using outlet control
Notch Full - set if the notch is full
Linear - set if using linearised equations at low head difference
Limited - set if orifice flow is limited or if culvert outlet free flow condition is limited to pipe full value
Trans - set if in transition zone between free and submerged
Nom HL - set if nominal headloss
Primed - set if siphon is primed
Switching - set if solver predicted negative head for flap in a previous iteration
Sub/Sup - set for subcritical free discharging culvert outlet, unset for supercritical free discharging culvert outlet
