algorithmic modeling for Rhino
I am trying to model a self-shaded freeform facade using Ladybug. The resulted mesh that I obtain from the 'shade' output from 'shadowRange' component looks incorrect or opposite. The meshes which should be sun-exposed are 'sun-shaded' in my model. Attached is the file. Need help to fix it. I would appreciate if somewone explain me the logic/algorithm to locate the 'self-shaded' meshes. Thanks. selfShadedFacade.gh

Flip the test geometry!
thanks Mostapha !...gr8 help :)
When I am calculating radition, it takes less time, and therefore, galapagos works smoothly. But, when I am calculating the shades (number shaded meshes) using 'shadowRange' component with the changing of parameter, it takes long time, and that is why, galapagos does not rum smoothly; in fact, it hangs. Any solution? My main aim is to do optimization of a free-from facade to get maximum number of self-shaded meshes. Thanks !
Iasef,
Try to use sunlight hours component for a single hour. That is basically the same as what you're trying to do and it is much faster.

In fact, I started my optimization with a single hour by fixing it 12:00 noon. Do I need any special command to make it 'singe hour'?
Thanks !
Attached is the ghfile. I feel difficulty to use sunlighthours component; there is no sunvectors, so I am not able to use it for shadowRange for finding self-shading meshes. Could you please check the attached file.
Thank you so much !
Dear Mostapha,
A great help ! Thanks a lot !
