¿How can I give rotation movement to a propeller?

Guillermo Rodríguez Pérez

I'm running a CFD to a cuadricopter drone and I want to analyze flux in the propellers. I have tried Motion>Rotation>Axis&velocity but it does not work. Any ideas?

Hi @Guillermo Rodríguez Pérez ,

 

I think your issue quite similar to these tutorials.

Maybe it can help you setting up boundary conditions.

If you are trying to do in steady state, you can use reference frame (on the cylindrical volume around the propeller) and specify rotational axis with rotational speed in terms of radians per second.
