specifiedSurfaceTemperature boundary condition

[human144]

Hello everybody,
I was wondering whether this boundary condition been validated? Or has anybody else had issues with this?

I am currently trying to reproduce Wind Tunnel experiments with specified floor surface temperature. However, the results don't make sense to me. In particular, the sign of the heat flux seems to be the same for both the stable as well as the unstable case.

Hence, I was wondering whether the implementation of this boundary condition is not fully finished and whether I still need to make some modifications to the code.
