Hello everyone,

I want to simulate the ventilation problem of a tall&large building. I am wondering why the wind direction at the bottom of the wind farm is downwards?

 

I want to simulate the temperature field in the room, but the current result is that the room temperature is still low with floor radiation. I think it may be a problem with the wind. Please give me some suggestions, thank you.

Can you show an image of the geometry (just show walls)?

Thank you very much for your help.

The images of the geometry are as follows:

1) This image shows the temperature of the walls(include windows)

2) This image shows the walls except windows:

In order to simulate the radiant floor, I placed a hot plate on the floor of the building (h=0.5m, energy sources: 140W/m3). I don't know if it is a hot plate problem?

Did you apply the heat to the wall or to a volume?

Yes,i apply heat flux on the floor. Actually, sometimes the wind direction of my case is right, but sometimes is not. Is there any problem with the mesh?
