algorithmic modeling for Rhino

AnchorPoints kangaroo system

so I made my own grid and i connect the surrounding points to anchorPoints to make a catenary shape

but after i turn the toggle to false, it just flies away.
on the other hand, when i did it with a hexagonal grid component, it did not fly away and anchorPoints remain on the ground and made a catenary shape.
Here is my file, could you help me with this?
Thanks

You've made your springs only over the full length of each line...you need to create segments from the intersections along each line and generate a unique spring for each one.  Your points with the unary forces applied are floating away because they aren't attached to any springs.
