Error Messages

These error messages appear when OHDA is unable to analyze a scenario. When these errors occur, the Apparent Sag, Cable Length, Critical Tension, and RTS results at the top of the preview screen are replaced with one of the following messages in red text.

Data is invalid. Fix errors and then click Calculate.	Appears when data is present that causes an error in the calculation engine. There are many reasons why this error will appear. Usually, OHDA will highlight the tab with the invalid data in red. Click the tab and the item causing the error will be displayed in red text. In many cases, clicking Calculate without making changes will open an Input Validation Errors popup window. Make note of the validation errors, then click OK and take the necessary steps to address those errors.
Conductor might be too small for the load or angle.	Appears when the horizontal tension is 0 or less. Common causes for receiving this warning can be a load case with high temperatures, load case with a large amount of ice, or a service drop spanning over 100 feet, to name a few.
Cross Arm Material - Not a valid option.	You receive this error if a cross arm material fails to load properly. The Miner and Miner\ArcFM Solution\Bin\PoleSpecXML directory holds XML files for specifications of pole material. You receive this error in Assembly Creator if the file for the material applied to the cross arm is missing or corrupt. You can also receive this error in OHDA because its calculation engine relies on the material of the cross arm to analyze weight and structural properties of the component. This error can occur when you press the Calculate button or upon application start regardless of whether or not corrupt cross arms are used in a scenario. To fix, you must either create a new PoleSpecXML file that matches the offending cross arms' material or edit all offending cross arms' to use a valid material inside Assembly Creator.
Configuration File Error - Error accessing Overhead Design Analysis configuration file. Changes cannot be saved and default values will be used.	This error typically means that User Access Control (UAC) is turned on in Windows and the current user does not have privileges to make changes to the local disk. You will need to give the current user proper authorization to make changes to avoid this error.
Clearance rule not found.	A cable in the design does not have a matching clearance rule for that cable and voltage. The administrator will need to use the clearance rules tool, or hand-edit the XML that defines clearance rules for your system, to fix this. The file that defines clearance rules is MinerStructuralAnalysis_ClearanceRulesSet.xml. Check the error log for information on which cable and voltage type was missing.
