Having multiple connectors to an air terminal,unable to compute pressure drop

[Anonymous]

Hello, I made a slot diffuser with array connectors (multiple connectors) it perfectly worked, but during pressure drop calculations, if more than one connection is set , the Revit shows a message "not computed" Can any one have a solution.

Make separate diffuser for each connector portion of a slot diffuser.

Hello,

ihave the same issue and Autodesk opened a case after my report:

The Development Team will try to make an initial assessment. The fix requires the code for Revit to be modified, and as such, we do not have a timeline for when any fix may be released.

The solution of @mhidshaji is the only solution at the moment.
