Hello;

I am trying to simulate a propeller blade for UAV in su2. I have created a mesh in pointwise and it is a simple mesh with cylindrical farfield and a propeller inside which I can solve easily using the su2 configuration file. However, I want to create a small cylinder inside the big one and then a propeller inside of it to get the better results but I couldn't figure out what should be the boundary conditions in that case and I also don't have ideas about the configuration file for this particular case. I have shared the word file. The configuration file is for the first picture, if someone can help me assign the boundary conditions for the picture two and share a configuration file for this case I would be greatful.

Thank You!
