Force Field - Vibrating Immerse Cantilever Problem - Fluent 6.3
 
Hi all.
I have to simulate the problem of a vibrating cantilever immersed in a viscous fluid.
The approach is 2D, at the moment: the cantilever is a straight wall and oscillates parallel to itself.
I have to fix the cantilever and let all the domain oscillate at the fixed amplitude and frequency.
Anybody may suggest me how to impose the force field, resulting from Navier Stokes-equations, to the default-interior points? It is a function of the time derivatives of both drive velocity and local (relative) velocities.

Unfortunately I have no idea of what kind of UDF I could use... :confused::confused:

Thanks in advance and the best regards

Herger
