Engineering Validation
The Engineering Validation item is used to define a set of validation rules to be used to check that InfoWorks network data is consistent with expected engineering values. These checks are carried out in addition to the normal network validation.
When an engineering validation item is first created, default built-in validation rules are supplied via the Engineering Validation dialog. New built in validation rules cannot be added, but existing ones can be switched on and off, and threshold values used by the rules can be changed.
User defined validation rules can also be created via the Engineering Validation dialog using a simple syntax similar to SQL statements. InfoWorks ICM includes a Validation Rule editor that allows you to easily build up your own rules without any knowledge of SQL.
Engineering validation is applied when an Engineering Validation object is selected in the Network Validation dialog.
An information message is displayed in the Output window for each item of data that is outside normal values. You can use this window to investigate the fields for which messages have been included.
