Pushing mass away from spheres

Hey guys!

I am working on a project in grasshopper.

I have a flat solid slab that I want to model using spheres.

Let me clarify: The mass should move by being pushed away from the spheres. (like in the drawing)

I have tried using a sine to create the geometry or copying mass from the spheres to the top of the slab but this isn't the result I want.

Does anyone know how to create this "attraction/repulsion" effect in a grasshopper script? Maybe with Kangaroo?

As you asked with a nice smile.

(Set Toggle to False, move slider slowly, assign points if needed, if the timer component is disabled or disconnected from Kangaroo reconnect/able it)

(Definition should be attached)

Your weaverbird is too old.

I am missing some components. The kangaroo one and the one between mesh and curve (square). Any idea why this is? When I open your file, it says:

"THere are two unrecognized objects in the file. Kangaroo Components 0.080 and Weaverbird 0.7.0.1"

I have kangaroo but am not sure about these components and I don't know how to get weaverbird. Sorry if these are really obvious questions :)

Thank you very much! That is exactly what we want.

Any idea how to make this work 3dimensionally? With a slab-mesh reacting to spheres instead of a surface reacting to circles?

Would be very appreciated!

Do you want the rolling action or is it just pushing locally? I remember the last model pushed away from underneath or inside. Is this a combination of both?

This might do the trick without weaverbird and kangaroo
