Discrete Phase model (DPM) particle break-up has particle size limits during particle tracking?

Hello, I am currently working on simulating water droplet partciles in a closed room. When I use uniform particles, without "particle break-up", I can carry out the simulation without any problem....

Is there a deep reason for using the squared modulus of the wave function as the probability density of the existence of the particle?

I think we were all surprised at the first time we got to know quantum mechanics that the squared modulus of the wave function is the probability density of the existence of the particle? The role...
