Sliding meshes and meshing
 

Hi I am modelling the flow over an object and to do this i have used a 3d cad model of a large domain with the object of iterest extruded from it. My question is this if i wanted to implement a sliding mesh how could i mesh it in pro-am? I need to create another circular surface within the domain so that i have an interface to slide. How would i set up pro-am to create this internal feature? Any help would be great Many thanks Joel
