Rotating reference frame problems

September 8, 2005, 17:29

I'm having problems creating the rotating domain for the model of a turbine. The problem is with zero radius.

Apparently it can't handle a rotating volume that doesn't have a hole in the middle. Is this true? How would you model a rotating disk then?

My turbine and hub are all rotating, so I don't know how to handle this. Any suggestions?

I would suggest you to simply add a hole on your geometry. It's ture that CFX does not allow to have a zreo radius in the rotating frame.

Regards!
