Keep tracking of aoa in rotating overset mesh
 

Hi, i'm simulating unstedy transonic flow over a pitching naca 0012.

The setup is:
-fixed background mesh
-rotating overset mesh around airfoil
- rotation point of the overset mesh is at 1/4 chord lenght
-main reference axes are fixed to the background mesh in corrispondence of leading edge when angle of attack is zero

Is there a way to print angle of attack at each iteration/time step?
