colopolo Member ^^ Join Date: Aug 2011 Posts: 70 Rep Power: 14	Hi all, I am trying to simulate wind induced free vibration of cylinder. Does anyone know how to write a UDF for vibrating cylinder in the vertical direction? I got a reference paper which is "CFD design of a generic controller for vortex-induced resonance" The author used UDF for moving boundary of cylinder but I have no idea how to write a UDF for VIV problem. Very thank you for any advises or help. Thanks
