I ran the ladybug several times and tried different time period, and it all turned out a lot of low sunlight hour at most of the site, which I think it’s impossible because the site is an open space. Don’t know what’s the problem.
I’ve tried to move the whole objects to the origin and adjust grid size, but it didn’t work as well. I will attach all the relevant files and internalized grasshopper fille.
Please have a look at it and thanks in advance.
