Please Help me to generate Vector Field Obstacle

Hello guys, I need your brilliant help

This is my site of project. I want to express the vector field of this site affected by forces from overpass and path bridge.

And I want to add some point charge which repels vector as obstacles around pond in the middle of site.


However, when I add some points on the pond’s boundary line for point charge, they are so strong to repel every vector to outsite.

But, I want to keep the most of vector spinning and affected naturally.

These are the files of Rhino and grasshopper.

you need to flatten the input of the merge fields component, not the output. Then up your point charges around the pond and increase the strength alot(~500)
