algorithmic modeling for Rhino

There doesn't seem to be a stable solution here... Nodes are pushed in from the edge at the bottle neck only to return later. This is 2d only. Lines show force.

Thanks Daniel!

Hi Dani, I just posted a similar definition here:


This one uses springs with cut-offs to push the particles apart, which seems to work a bit better than power law repulsion forces for this. The value of the rest-length/cutoff can take a bit of adjusting though to find the ideal value for a particular surface.

Great job, i am working in something similar, but still getting familiar with kangaroo,  any source definition avaible?

The ideal solution for a particle cloud that experience inverse squared force is indeed a state where all particles are squished against the edges (at least with a circular and rectangular boundary). Use inverse cube or higher if you want them to populate the interior of the container as well.
