How can I see the periodic diaphragm motion in fluent display??
 

Hi ;
I am trying to simulate the periodic diaphragm movement. For this, the diaphragm displacement was expressed as :
y = A sin (ωt)
where A is the diaphragm amplitude, ω is the angular frequency and t is time.
Does anyone know how to formulate a UDF in order to combine it with the FLUENT solver to describe the periodic diaphragm movement .
Very thank you for any advises or help.

Thanks
