Issue in solar hour analysis

#1

Hi,
I am analyzing solar hours for a building, and now it is analyzing outside surfaces of the building. I made this building in the Grasshopper, so I don’t know how I can change the normal face of the surfaces so that I analyze the inside of the surfaces. Would you please help me to solve this issue? I attach the model here.
Thanks.

@htaheri,
Use Flip or mesh flip components to flip the normal of the surfaces or mesh surfaces.

Thanks.
I tried that, but some of the components that I am using are not working with mesh. Is it the only way to reverse the normal of the surfaces?
