Direct Sun Hours analysis

Hi everyone, I am trying to make a shadow analysis of one hour of my geometry by using the Direct Sun Hours command. Everything looks working, but some points (squares) that should be definitely in shadow are showed as on sun.

Can anyone help with how to make this correct?

Thanks :slight_smile:

I tried a similar file at my end and the results seem fine. It would help if you could share a GH file.

thanks for the reply, the files are attached here:
