buoyancy lift & Buoyancy drag on a moving paddle
 

Good Day Friends,

Kindly see this you tube link [ http://www.youtube.com/watch?v=2pP2hFbcqw4 ]

I already design this vehicle in catia. I want to see the buoyancy lift & Buoyancy drag. I create mesh in ICEM CFD, But I want to flap all the paddle up & down. In fluent UDF is there, but I want to do in Open Foam is Its Possible?

For example if left side paddle flaps very less speed when compared to right side paddle it turns left, similarly for all orientation ie pitch,roll, Hovering ( its all depends the variation of speed in that paddle)

Kindly give your suggestion, how I can solve and set case file for this problem in open foam.

Thanks for your valuable time
