Hello all

I am trying to solve a problem with dynamic mesh.
Consider concentric cylinders, both having a oscillatory motion in opposite directions. But the far end of the domain in fixed.
I created two different meshed for both the cylinders and merged the meshed (just like oscillatingACMI tutorial).
The case runs fine accept that the quality of mesh degrades gradually because the node points at the ACMI patch remain fixed to the patch. Can anyone suggest an appropriate boundary condition at the patch so that the nodes slip at the patch.
I tried using fixedNormalSlip (used in potentialFreeSurfaceDyMFoam tutoria), but dose't solve the propose.
