Hello everyone,
I am investigating the circumfential velocity in front of a turbomachine.

I want to initialize the cylindrical coordinates for all parts in CFD Post.
As long as the parts are symmetric in the axis I use the turbo mode. But I have a tilted cone which has no "hub" or "shroud", only a rotating axis which isnt consistent (see the picture).
Thats why the two point axis wouldn`t be accurate.
I havent found anything towards this topic yet.
Is it possible to write some kind of script to change the coordinates in post?

Plan B would be for me to insert planes in post along the Z axis and extract the velocities and calculate them into polarcoordinates to get the circumfential velocities atleast at some areas.

Has anyone else had experience with that or ideas where I can read about that topic? I would be grateful for answers.
Like always... thanks in advance
Anny
