Fluent 2022R2

      When I try to rerun several old simulations built in Fluent 2017/2019/2020 in the current Fluent 2022R2, the results are basically wrong and totally off from what I had before.  How can I convert an old Fluent case file to make it compactible with the current version?

       

      Thanks a lot for helps.

      In particular, in the old version, I used the RNG k-e and cavitation model which gives a stable results.  However, using RNG now makes the flow to become supersonic while the cavitation does not produce and vapour.  I changed nothing in my model.
