When beta features are enabled, the Fluent Meshing guided workflow's Extrude Volume Mesh task includes an additional Method when extruding volume meshes. If translational periodic boundaries have been defined in the Set Up Periodic Boundaries task (Setting Up Periodic Boundaries), you can extrude the selected translational periodic face to its shadow face using the Extend to Periodic Pair method, and setting the remaining options. Note that when defining the translational periodic boundary, the periodic and shadow faces should be connected to two different cell zones.
