How to Oscillating Airfoil (3D) at distance of 0.25 of chord length?
 

My case is a 3D Problem with an airfoil. I want to oscillate the airfoil at 1/4 th (i.e at 0.25 meter)of the chord length.

The total length of an airfoil is 1 meter.
My airfoil is oscillating correctly but about origin at chord length of 0 meter which is my leading edge tip.
So actually i want to oscilate it at a distance of 0.25 meter.

So i want to oscillate exactly as in the link below

Hope to hear from anyone soon.
Thanks
