Hi all ,


i search how to use drag and lift forces in my udf . in order to create a motion of a pipe . I already have a udf compiled who can move my pipe but my motion is rule by a simple equation sinusoidale .

i have a better theorical model who use the drag and lift forces to calcul the dynamic velocity at each time step .

I just don't know how ask fluent to give me the drag and lift force he compute automaticly at each steps .


thanks you
