Best way to avoid intercollision in particle sim

Recommended Posts

There will be something between 1-100k particles. I need to avoid that the particles intersect with each other to avoid flickering, since the particles are used to instance small geo forms with different colors. In case they do intersect, it's easily visible.

To my mind come the regular forces and a mixed approach with grains. Since I want to achieve a very fluent movement without abrupt changes in speed (stuttering), I wonder whether forces and grains on their own will do the job. Wouldn't be something like a collision avoidance algorythmn be needed? Something which determines if the particles will crash if they continue to be simmed with the current v.

I played around with flocking behaviour lately mainly with POP Interact to seperate the particles and a sop solver to align v of neighbouring particles. Could this be a solution?

Any experiences/ideas?

Cheers
Tom
