Keeler Gap Sim ?
08/21/16 at 00:55:11
 
I came upon this link , dealing with the Keeler Gap near Saturn where te moon Daphnis seems to make some waves on the ring nearby , as it passes the ring particles .

I wonder if this aspect ( waves ) may be simulated with Gravity Simulator ?  
Haven't tried yet myself.

I saw the same article you did and wondered the same. It would take a lot of particles and probably run prohibitively slow. I can see why the moon would disrupt the rings, but I can't see why the rings would settle back to normal after the moon passed.

I agree , I also cannot see why the particles return to the normal plane , except if one takes into account inelastic collisions between particles .  
If there is no dissipation of energy one would observe a ring with ever lasting fringes I imagine .

Googling for "Keeler Gap" , I came upon this link . Nice animations . Seems indeed the Keeler Gap Waves need indeed some model of inelastic modelling .
