Time variable irradiation

[mimim34]

Hello everyone. Hope you're all doing well.

I'd like to add a table of solar radiation measures taken every 30 mn daily (for a month). However, I have failed to find a way to do that, other than creating multiple files for each radiation measure.

That would mean if I take measures from 7:00 am to 7:00 pm, every 30 mn (yielding 24 measures a day) for 31 days, I would need to create 24*31=744 files, which is practically impossible.

So my question is, does anyone know of a feature on Tonatiuh that lets you insert time varying input measures (within the same file)?

Also, no units are mentioned on Tonatiuh. So I'm also wondering whether the flux distribution is in W/m^2 (as stated in a YouTube video) or in another unit?

Thanks for helping me.

Hello:
Tonatiuh does not define units, because you can model your system in whatever units you prefer: meters, millimeters. Consequently, irradiance must be specified in consistent units. For example, if you are modeling the system in meters, you should use W/m2 for the irradiance.

If you need to simulate several sun positions in Tonatiuh for the same system you can use the scripting functionality for that puropose. In the following links you can find a tutorials the available functions in the scripting:
