Hello
why does my simulation have this lumpy effect?
My voxel and particle size on the emitter, collision and mesher are at 0.002.
(On the mesher I don't want to push too much the smoother to keep the collision shape)

Remember, your particle separation is a divisor against your domain size. Its efficacy is based on the domain it is dividing. Shrink your red domain box to increase your resolution (and physical memory usage) while keeping your particle separation the same.

For the domain, I understand tht the voxel size is the number of cube/voxel in it, more voxel = higher resolution but longer to compute.
For the particle separation it is not so clear for me, and the balance between voxel and particle sep is not easy to find :/
