Hi,

I am trying to simulate an engine with entire geometry includes
rotors, stators and diffusers. the engine is located inside a wind tunnel.
I am using single reference frame (SRF) to rotate the rotors.
However, I read below information

For a rotating reference frame, FLUENT assumes by default that all walls rotate at the speed of the moving reference frame, and hence are moving with respect to the stationary (absolute) reference frame. To specify a non-rotating wall, you must specify a rotational speed of 0 in the absolute frame..

As a result, I have many walls such as stators and wind tunnel surface which are non-rotating.

my query, Is it a good way to utilize the SRF by defining all walls with 0 velocity except rotors?
