Trace Nodes
|
Up to ten trace nodes can be selected.
| 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.
|
| Dominant Trace Tolerance (%)
|
Provides percent tolerance to the dominant trace results based your preference.
The default value in the application is 5%.
You can input higher tolerances based on your requirement.
|
| 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 drop-down 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.
