UDF for oscillating cylinder
 

Hello,

I Need to model a 2D turbulent flow past an oscillating cylinder. The cylinder is oscillating transversely to the flow and the instantaneous displacement must be form: depl= Asin(wt), A=amplitude,w=pulsation. Does Somebody have an UDF to do defined this type of movement on the cylinder and to export (in an ASCII file) the time histories of lift and drag coeff. forces ?

Thanks by advance. (PS : sorry for my poor english, my native language is Frensh !:))
