Recently i'm a master student in major of architecture. My assignment is about 2D heat transfer through water on roof top. I have question about how to setting top water boundary that opening to sky. When we will calculate about heat transfer we use "Surface to Ambient" and setting ambient temperature.
so I think this solar radiation rate is uniform, right? ><
But my assumption must setting solar radiation by sun direction (rate will not same all day)
How to setting solar radiation rate depending on sun direction? I have weather data about that but I don't know how to input that in COMSOL.
Sorry about my english isn't good as well, Please looking my diagram that I attach
Thank you for your kindness
