Circular Pattern to Reduce Solar Gain Conficting with Surface

Hi Everyone,

It is my first time to use ladybug and I am facing some difficulties that I could not solve. I am trying to create bigger circles for harmful radiation and smaller circles for helpful radiation i.e. circular pattern to reduce solar gain on ETFE skin (reference: Responsive facade based on radiation results)

My first issue is the extreme negative result value for the net solar benefit. I am not sure if there is an error in the data that caused such a negative value (-660435).

My second problem is the circles on the surface/geometry
The circles are cutting through the geometry. Is there a way to orient or to project them correctly onto the surface?

Thanks in advance!
