Dear Omar, the automatic calculation of the convective heat transfer coefficient is only valid and it only works for the inner surface of a wall. This error
message means that you’ve activated the automatic calculation on the outer surface, by setting the option “internal calculation” on the heat transfer coefficient “back” in the wall type manager, this is only allowed for surfaces adjacent to two thermal zones.
Just switch it to user-defined and choose a standard value e.g. 64 kJ/(hm²K) for external walls or 11 kJ/(hm²K) for internal walls. Best __________________________________________________________________________________________________ Jochen
