Hi Nick,

Thank you so much for this!

I’ve managed to find the TUI command to change ids of face zones, which is what I’m trying to do. However, there is now a strange problem.

I tried to change the id of a face zone from being ‘430’ to ‘444’ [based on the comparison of ids between the 2 meshes], but when I do that, fluent meshing throws an error saying “Zone with id 444 already exists”.

However when I ask it for the zone with id ‘444’, it says “Invalid zone”. You can see this here:

zone id error

I also checked if there were any cell zones with this id, but sadly, I couldn’t find it there either. I’ve hit a brick wall again and have no idea what to do
