Trace Nodes
|
Up to ten trace nodes can be selected.
| Selection |
Selection List |
You can add a
selection list of trace nodes to this box. If there
are more than ten nodes in the chosen selection list, a warning message
will be displayed and the first ten node names will be used to populate
the grid. |
| Grid |
You can add up to ten trace nodes to this grid either by applying a selection list (see above) or by selecting node names from the dropdown list in each row. |
When trace nodes are selected, additional reporting facilities are
available for tracking blending of water from different sources:
- Additional fields in the node results grid reporting:
- The percentage of water at the node that has
originated from each trace node
- The trace node that acts as the dominant source,
providing most of the water reaching the node. (Note that there may not
be a dominant source, or it may not be possible to derive the dominant
source.)
- Additional graphing options to graph Trace(%)
of water at a node that has originated from the trace node(s) and to graph
the dominant source.

| Solute |
|
Solute Data
|
For adding the Solute Data object containing
the water quality parameters to be used during the simulation. |
| Display area |
Displays the values
defined in the solute data object (see above) or, if no solute data object is selected, the default values that will be used instead. |
See the Solute Data topic for parameter
details.
|
| Turbidity |
| Do Turbidity Analysis |
If checked, includes turbidity analysis when carrying out the simulation.
|
|
|
Stagnant Threshold
|
Stagnant water flow threshold - computational accuracy for water quality calculations.
Default value
is hydraulic computational accuracy specified on the Schedule
Hydraulic Run view.
|
|
Water Quality Timestep
|
Water quality calculation frequency. Default value is 10% of the hydraulic
timestep specified on the Schedule
Hydraulic Run view.
|
| Lagrangian Solver |
| Use Lagrangian Solver |
If checked, a Lagrangian time-based approach to track movement and blending of water through the network will be used.
If this option is unchecked (default), InfoWorks WS Pro uses an Eulerian water quality model.
|
|
Age Tolerance
|
Tolerance value used by water quality solver to determine whether to create a new segment of water or to blend it with the existing nearest segment when moving water into the top of a pipe.
|
| Concentration Tolerance |
See Age Tolerance above. |
| Trace Tolerance |
See Age Tolerance above. |
| Turbidity Tolerance |
See Age Tolerance above. |
