Validating demand area

Step-by-step Guide

In InfoWorks WS Pro, a demand area must be valid before it can be used to update the network or demand diagrams. During validation, the demand area is checked for missing values, errors, and inconsistencies that may affect the flow balance and calculations.

Demand areas generated from area codes or polygons can be validated with the Demand Area grid open. Their status automatically updates in the Validation column. When opening the Demand Area grid, validation is carried out on all demand areas. Any errors are displayed in the validation dialog box.

To review errors listed in the Validation column:

1. In the Demand Area grid, select a demand area.
2. Right-click the demand area and select Update Demand Area to display the validation dialog box.

3. Make changes within the grid to remedy the errors.

Once all the demand areas are valid, the network and demand diagrams can be updated.

4. Ensure that the network, control, and demand diagram are open.
5. In the Demand Area grid, select the demand area.
6. Right-click the table margin and select Update demand diagram and network.
7. In the Update Demand Diagram and Network dialog box, in the Leakage group box, select Property-Based Demand.

This updates the Specific Consumption values in the Demand Grid on the Node Demand Page with Specific Consumption calculated from Demand Area Analysis.

8. Click OK.
9. In the Demand Diagram, open the DMA35Dom profile. A demand profile is now populated for this category of user.

Validating demand areas and mitigating errors ensures data accuracy and informs decision-making around infrastructure planning and maintenance.
