Error 231 - SUPPORT: skirt missing. appears when running analysis in AutoPIPE Vessel, why?


Answer:

This error occurs when a vessel is initially created with support type "Vessel on Skirt" and then convert to support type "Brackets" followed by deleting the skirt. In AutoPIPE Vessel, the support type is a fundamental property that is fixed at the time of vessel creation.

Changing the support type from "Vessel on Skirt" to "Bracket" after creation is not supported. Only the following support-type changes are supported in AutoPIPE Vessel:

Workaround:
To avoid or resolve Error 695, use one of the following workarounds: (assuming "Vessel on skirt" was selected during creation) 
Option #1:

Option #2:

Try the following:


Option #3:
