Currently, AutoPIPE Vessel (v46.00.00.165) does not account for nozzle external loads in roof thickness calculations. As an alternative, user can evaluate the stresses caused by external nozzle loads separately in component mode.
To do this, create a new file by navigating to File > New > Component Design > Local Loads, and then check the stresses.
If you believe this would be a valuable enhancement and would like to propose it as a new feature in AutoPIPE Vessel, please refer to the attached Knowledge Base article for instructions on how to submit a new IDEA for future consideration.
