FLIP: particle separation vs particle radius scale?

[catchyid]

Hi,

according to documentation "particle radius scale" is defined with respect to "particle separation" as

Quote

The radius of the particles is determined by scaling the Particle Separation by this parameter

Now, I am confused: if particle separation is 0.1 then the max particle radius should be 0.1/2 otherwise particles would be colliding with each other? I feel these two parameters should be tied automatically and not defined independently (e.g. if particle separation is 0.1 then particle radius must be less than 0.1/2). Also, if I say particle separation is 0.1 and particle radius is 0.5 then would that mean I would have partially empty voxels? I am confused as you can tell! Any help is appreciated

As far as I understand, to get the radius of a particle it will take the particle separation value and scale it with the particle radius scale.

so if the particle separation is 0.1 and particle radius scale is 0.5 then the true radius of the particle is 0.1*0.5.
