Direct Radiation result is Wrong on LadyBug!

[jamparc]

Hello devang,

I tested on different conditions and concluded that my question needs to be updated.
I made a new article and shared weather data and GH file there.

Direct Radiation includes Circumsolar Radiation?

Hello, After running a single hour simulation for the direct radiation, I had a question why the result shows more than two different radiation values on my facade. I checked with SkyDome component, and then realized that the single hour direct radiation includes more than one sun-vector or radiation value on the patched sky! I tried to understand the python code, but failed… Will you explain how LadyBug calculates the direct radiation on the geometry? What is the reference for this approac…

Thanks.
