Note: Although you the user now can edit the list of FUs using the Edit » Functional Units » List menu item, this is not recommended FUs even FUs have been assigned in the Geographic Wizard, the user needs to be careful to process the modification as it may result in the loss of any model definition and settings of the deleted FU(s). Functional Unit names cannot be modified once they have been assigned in the Geographic Wizardlinked to other models (e.g., calibration model, water quality models), and change of the results. |
