Greeting to all people in this forum!

I am struggling with the following topic related to Fluent. I went through the Fluent user manual several time, but I could not find a definitive answer to my current problem and therefore I am seeking the help of expert users that faced a similar issue.

The problem is the following one:
I am using Fluent and I have a computational domain that involves a moving body and I would like to perform adaptive mesh refinement in this domain.

To deal with the moving body, one strategy could be to use remeshing. However, it seems that remeshing is not compatible with the PUMA algorithm(polyhedral unstructured mesh adoption) that is the default method recommended in the Fluent manual for adaptivity.

Therefore, my question is: what would you suggest if I want to perform adaptive mesh refinement in a computational domain involving a moving body? Do you have suggestions based on past experiences? If this is the case could you describe your approach, the challenges that you faced and the possible limitations?

I have also seen that Fluent has this overset mesh functionality for moving body, but I am not so familiar with it. In case you have also suggestions in this direction, please let me know.

I am really open to hear and discover new approach that I might have not considered since they did not come to my mind.


Thanks in advance for your help and I am looking forward to a fruitful discussion
