modeling droplet falling to the bottom problem?
 

Hi, I'm trying to figure out which setting is necessary to simulating droplet behavior properly, which is a simple droplet falling toward the flat surface, for practice.
I applied gravity, surface tension and viscous flow modules.

What I thought is that the droplet is broken into small particles and splashed in all directions after the impaction of the droplet with the bottom side,
but the simulation result is that the droplet is just spread on the bottom side, coated thinly until it arrives at the mesh boundary. (I didn't set boundary condition as I'm just interested in droplet splashing part)

Is there anyone who can guess the reason for this phenomena or point out what I thought improperly, it would be a great help for me and I appreciate.

Hello,

If the droplet has sufficient velocity relative to the restoring forces of surface tension
and viscosity, the simulation should indeed show droplet breakup.

It will be helpful to compute relevant non-dimensional parameters such as the Weber
number and the Bond number to gauge the relative importance of the physical properties. It sounds like the viscosity of the droplet is very high. Or possibly the
surface tension coefficient is too low?
