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 .

http://www.universetoday.com/130351/new-jpl-visualization-waves-saturns-rings-pu ts-keeler-gap/

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

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 .

Seems indeed the Keeler Gap Waves need indeed some model of inelastic modelling . http://www.cs.trinity.edu/~mlewis/Rings/KeelerGap2005/
