Configure the InfoSurge Pro model options

Step-by-step guide

When using InfoSurge Pro, it is important to properly set the model input units and hydraulic properties, including the headloss equation method, before running a simulation.

1. From the Model Explorer, Operation tab, expand Simulation Options.
2. Double-click BASE Simulation Options.

3. From the Simulation Options dialog box, select the General tab.
4. In the Hydraulics section, for this example, expand the Flow Unit drop-down and select Gallons/Minute.

This sets the input data, such as elevations and diameters, to US imperial units. These flow units are applied to link flows and nodal demands.

5. Expand the Pressure Unit drop-down and select PSI.
6. In the Headloss Equation drop-down, select the Hazen-Williams headloss formula for hydraulic analysis.

This choice of equation also determines how the roughness attribute of pipes is interpreted.

7. Click OK to close the dialog box.

These options are saved as a permanent part of the project.
