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.
