Hello everyone

I'm working on a project with the aim to calculate the heating of a photovoltaic modul due to solar radiation. I chose the chtMulitRegionSimple solver becaus i would like to have the temperature distribution in the modul. Based on the tutorial multiRegionHeaterRadiation i built up my case consisting of two Domains, a fluid and a solid one. The fluid region is more or less a big room with air and the solid region represents my photovoltaic modul and is just a rectangular plate in the fluid domain. For the radiation model i chose the fvDOM model. Now i have to problems:

1) How can i make a radiation source boundary condition at the top of my fluid domain to represent the solar radiation energy?

2)Due to the fact, that solar radiation is directional depending on the month, day etc. i have to implement this radiation source boundary condition as a directional radiation source. Is this possible with the fvDOM model?

Thank you all for helping me in advance!

best regards.
