Working with engineering validation
The Engineering Validation object is used to define a set of additional checks on network data to ensure that it is consistent with expected engineering values.
Engineering validation is applied when you select Do Engineering Validation in the Network Validation dialog and add an Engineering Validation object to the selection box.
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.
Creating an Engineering Validation object
In order to create a new Engineering Validation object, you must first create an Engineering Validation Group inside a Model Group. See Creating groups within a model group and Creating a database object within a group for more information.
The Engineering Validation object is created with default rules and values already included. You cannot add new validation rules, but you can switch rules on and off, and change the threshold values used by any of the rules.
Modifying engineering validation rules
A set of default rules are displayed in the Engineering Validation dialog. Any of the validation rules can be modified:
- The Modified by User column indicates which rules you have changed.
- You can disable a validation rule by clicking the Check Rule box. Click again to restore the rule.
- You can enable or disable all the validation rules at once. To do this, right-click the Engineering Validation dialog and choose Enable all or Disable all from the context menu.
- Each rule can be assigned a Priority Level, which is shown in the Output window. By default, engineering validation rules are given a priority of 3. You can change this to any numeric value. For serious errors or warnings, you can set the priority level to 1 or 2, respectively.
- The Minimum and Maximum values against which the data is checked can be edited, where appropriate. The Units are shown in each case.
To use the new set of validation rules, you must specify the engineering validation object in the selection box on the Network Validation dialog.
Default validation messages
The following messages are displayed by the default engineering validation rules.
In the Check Rule column in the table below:
- 1 means display warning if fails validation
- 0 means ignore
