[TRNSYS-users] Type56a: Automatic Heat Transfer Calculation Error

[Adrien JEZEQUEL - ITF]

Dear Paul

Your issue concerns Convective Heat Transfer Coefficient of wall in wall 
type manager.
You certainly select an internal calculation for an external wall in 
your bui file, instead of userdefined.
Message error indicates that automatic heat transfer calculation is only 
allowed on surface within a zone.

Best regards
