Dear Paul
Internal calculation is not ok for back surface of external wall.
You most also choose "userdefined" calculation for that
Wall.

Hi Adrien,
I select "internal calculation" for "Convective Heat Transfer
Coefficient of Wall" for all my wall types; back and front. Is this
wrong?
Kind Regards
Paul

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.

Hi All
I have an error reported on a simulation run and need some suggestions as to what could be going wrong.
Fatal error at time 0.00
Generated by unit 3
Generated by Type56a
Message Error in automatic heat transfer calcualtation for surface 7 or it's adjacent surface. Automatic heat transfer calculation is only allowed on surface within a zone. Please check input file .bui
This is different to the example posted erlier in the year. I am modeling underfloor heating here.
I tried deleting the surface 7 but this does not change the report. I still refers to surface 7.
Any clues? I can forward the .bui file if interested.
Kind Regards
Paul
