Help needed with moving parts
 

Hi everyone!

I'd like to ask you to help me with proper setup of CFD simulation of moving parts. I'm new to CFD world and to Autodesk Simulation CFD.

I have a part like the one attached.

It rotates around shaft forced with water flow (it's some kind of turbine). Wing consists of two "flaps". They ought to be closed when water pushes wing and should open when it moves against water to reduce drag. I can setup angular motion for wing frame around shaft but I cannot properly setup flaps to rotate around theirs shafts AND move around with whole wing :/
I hope I described my problem quite well.

Can somebody help me / guide me to properly setup the motion settings for this simulation?
