<font size="-1"><font face="Arial">Dear Paul<br>
<br>
Your issue concerns Convective Heat Transfer </font></font><font size="-1"><font face="Arial">Coefficient of wall in wall type manager.<br>
You certainly select an internal calculation for an external wall in
your bui file, instead of userdefined.</font></font><br>
Message error indicates that automatic heat transfer calculation is
only allowed on surface within a zone.<br>
<br>
Best regards<br>
