Hello to everyone. I am performing an study on how the temperature varies in a block that has a thin thickness but has air inside. This block is exposed to a cold air current. I want to see the wake of different temperatures but when I plot it the only thing I get is a very small gradient around the whole block, so I think I am doing something wrong.
The boundary conditions that I have put is that the walls are coupled with the fluid domain and have a temperature of 25ºC, as well as the conditions for the inlet and the outlet. What could be the problem?

Theoretically this box is representing a building, so the heat is coming from heating of the building, which should be enough to maintain it at 25ºC when there is no wind. The idea is to evaluate the effect of the wind on the thermal efficiency of the buidling.
Should I model this heating with a heat generation rate?
Thank you so much for answering!

So when there is wind you expect the building temperature to drop?

Exactly, at least at the front where the ariflow impacts and at the corners where the velocity is higher. I also expect to see a wake of temperature but I don't know if this is possible. The idea is to relate the temperature distribution with the one of the velocity, which is the one shown in the picture below

I'd suggest plotting velocity, that'll give a clearer image. You may see a temperature wake, but you may also need to adjust the scale to see this.

It's all clear now, thank you so much!
