Dear Fluid Ppl,

Good Day,

I have worked with Rotating regions upto 2015 Flow Simulation where RRF are used and wondering, if you can throw some light on Technical differences between following pls,

1. Single Rotating Region -Vs- Multiple Rotating Region.

2. Averaging Technique -Vs- Sliding Technique

Note:- In Sliding Mesh, does rotor/solids are moved in spite of traditional fluid movement ?

Cheers,
