please check this video.
I'm simulating sand and it's way easier to do it in maya with nparticles than in houdini.
Apparently there is no way to make particles self colliding in houdini. in pop there is a interact but it's not exactly working in this sense.
In dop we have particle object but apparently is meant to do mainly SPH simulations, maybe we could use this? i don't know how to set it up anyway.
I want avoid using flip with varying viscosity because it result like mud.
Rigid body also is too slow given the amount of grains i need to simulate over and over.
i also found this video with blender, it seems it uses SPH, but it's not clear to me.

is there a way to have particle self collision in houdini?
thank you in advance
