Hello,
I'm a master student, and I'm using Wufi 3D Plus. In order to understand whitch kind of calculation wufi does, I create a box with external walls composed by one material from the default database.
I'm checking the results about heat flux and temperature in the components (envelope wall), and I have a doubt: why the heat flux on the external surface is the same for every exposure? Shouldn't be different according to the exposure? I read on FAQ that the heat flux is the combination of the heat flux through the component and the contribution of the solar radiation, did I have understand well? In my simulation the heat flux is the same for every exposure.
Could you help me to solve this problem, please? It will be very useful for the development of my thesis!
Thanks in advance,
Tiziana
