Contacting moving bodies
 

Hi all,

I am trying to simulate a flow around two circles. One of the circles stands still, the other one slides around it so that their surfaces touch each other. I have already modeled this without contact, with a minute mesh between them. But it is essential that there is no gap between the circles, this the whole idea of the simulation.
As far as I understand sliding mesh slides only two meshes, but I need to slide walls.

Thanks
