Product Name:

Version: Error Number:


All Versions WN20-16


Brief Description of Error:

NUCALCU - When a Fault Tree with an undeveloped gate is linked into another fault tree, no warning or error message is displayed and an arbitrary gate is used in place of the undeveloped gate.  An undeveloped gate is a gate created by the insertion of an internal transfer gate and does not have a type assigned.  In the fault tree editor, an undeveloped gate is displayed with a question mark instead of a gate type.

However, a proper error message is displayed, when the fault tree with an undeveloped gate is linked, instead of being linked into another tree.


Possible Effects on Results:

The linked fault tree will have a different gate in place of the undeveloped gate.


Problem Classification:


Editorial Error  


Software Anomaly  




Workaround Suggestions:

Make sure that there are no undeveloped gates in the fault trees of your model.


Correction Status:

Fixed in SR-3 of 2.0.
