ANY FLUENT WIZARD AROUND??
 

Hi all,

I am looking for a UDF that calculates the integral of the pressure forces (resultant of lift and drag) for an incompressible flow past a cylinder in 2d. Then, via a certain differential equation -not known yet- the displacement of the cylinder's center of gravity will be calculated then fed to the solver to move the whole cylinder and the mesh consequently. That is supposed to be made in transient simulation of course. So, this UDF will be used in the moving mesh model so as the simulation works as a coupled fluid-structure interaction.

Now, could any body give a hand here?

Cheers, Amr
