Unstady and time specrtal analysis- How to set up?

[PedroCardoso-mdo]

Your options indicate capabilities for performing unsteady and time spectral analysis. Is there any example of how to perform this with ADFlow? My goal would be to even use a mesh that moves to simulate a propeller, I got the idea when reading the source code that this would be possible, however, I am unable to understand how I can do it.
