Hi All

I tried to model the heat source (radiator) inside the room, I managed to model and meshing it, now the problem is applying the boundary condition as I am facing the problem (I have attached the error in the below presentation)

problem description
I want heat source to produce specified heat (say 20 Watts) and I want to see how much time the air in the room will take to reach target temperature (say25 degC)

Can you please give me some tips over it on how to consider

Thanks in Advance

Check the list of Location used for the boundary Heat Source/Heat Capacity.

It seems you have selected the same mesh region twice for two different boundaries.

From the pictures, it is difficult to see if the mesh for Room also contain the volume for Heat Source (hope not)
