I'm trying to model a mixer using the sliding mesh method and I've been having trouble getting a good quality mesh across the interface. I've tried using separate parts and then used the contact sizer in the Meshing program but that hasn't helped. I've found that I can get a good quality mesh if I create everything using a single part but that means that I no longer have an interface to allow the blades to spin; So I was wondering if it was possible in either FLUENT or Meshing to split a conformal mesh into an interface along a wall or other named face?

If you want to go from an MRF model setup to a sliding mesh setup, use the following text command:
mesh → modify-zones → mrf-to-sliding-mesh
To successfully switch from an MRF to a sliding mesh, you must provide the ID of the fluid zone. ANSYS Fluent identifies all the zones belonging to this fluid zone, as well as fluid zones shared in the domain. ANSYS Fluent then splits these zones into walls, after which the walls are slit converted to interfaces. ANSYS Fluent then changes the cell zone condition of the fluid zone to Moving Mesh in the Fluid Dialog Box. Note that the interface between the cells zones should be an interior boundary.

That's exactly what I was looking for and it looks like it was worked perfectly, thank you so very much.

HI.Mr.protussa
I encouretred the same problem and i tried to use your solution ,but i didn't find where to set :
mesh → modify-zones → mrf-to-sliding-mesh
I am using ANSYS Fluent 16
If it's possible more details for how to set (mesh → modify-zones → mrf-to-sliding-mesh) with pictures
THANKS
