How to create a full model from a rotational periodic segment model in Fluent?

Rotational periodic geometries are often simulated using only one segment. Sometimes a full model should be generated starting from the existing segment model. In Fluent this can be done by doing the following steps:
1)Read in the segment case
2)Rotate this segment by the number of degrees the segment has (Setting Up Domain -> Transform -> Rotate)
3)Append the original segment case (Setting Up Domain -> Append -> Append Case File)
4)Fuse the mesh nodes at the overlapping faces (Setting Up Domain -> Combine -> Fuse) 5)
Repeat Step 2-4 until the full model is created.
After reading in the original case the last time, two fuse operations are needed. If the periodic faces have no matching meshes you have to use non-conformal interfaces instead of the fuse command (Setting Up Domain -> Mesh&help). When appending a case file to an existing case with the same boundary names they will be automatically changed. You can avoid this by renaming the boundaries before appending a case.
At the end you will have the boundaries as segments. You can unite them using Setting Up Domain -> Combine -> Merge.
