As far as I know, there is no slide mesh function per say; however, deal.ii does have a rotate mesh function which is pretty straightforward to use. Presumably if you apply a cylindrical mesh in the airgap with a known number of uniform segments, you can rotate the mesh by an angle corresponding to the number of segments and the nodes will always match up. In my experience, generating this type of mesh is very difficult from within Deal.ii itself, but presumably you can get this mesh from an external program, I would think it would be straight forward. I am attempting to create a geometry with slide mesh as well.
