cohesive behavior optimization problem

[CKJK]

Hello all, I am simulating a coalescence process of two water droplets, but I found the visualization effect not that realistic. Besides, whether the two interaction surfaces are two halves of two spheres, or two whole spheres, the effect is the same. The left half of left sphere and the right half of right sphere seem not changing at all, they only translate as a whole.

Could anyone help give some advices that make the simulation more realistic? Thanks a lot in advance!! I attached my .cae file here~

To achieve more realistic effect you would have to refine the mesh and adjust material properties. Also, are these droplets supposed to be hollow ? Are you sure that the shell thickness is correct ?

You're correct, solid sphere looks better!
