Hi Samcfd,
I am doing something similar i have applied the udf to the airfoil with a 20deg pitching amplitude and set the fluid as deforming but i keep getting negative volume detected and i have changed some of the settings but problem persists, did you eventually sort out the problem you were having?

I am looking to find a solution to my problem. So I found your response to some student and I hope to help me. I want to simulate an elbow artery by using dynamic mesh. I need to apply eq Ra(t)=0.4+20sin 7.89*t That can apply it on the wall and it will expand and converge according to the eq.. Please could you help me to write the right code as a UDF? Thank you very much Note: I have attached some file refer to the geometry and derivatives eqs Best regards

I would like some advice about this problem I would like to use moving mesh or dynamic mesh with UDF for Morphing Airfoil I don't know how to use it. Please give me some advice. I'm student and leaning to this project I don't look your link on sharing would you please to sent to me at my Email? : agisan.r@gmail.com Sittisak. Thank you very much.
