Hi everybody,

I am currently simulating a helicopter rotor. As the rotor rotates the blades change in pitch. I'm using a rotational motion for the rotor and morphing motion for simulating the blades pitch rotation. The pitch of a blade is given by this equation:

Theta = Theta_o + Theta_1c*Cos(azimuth angle) + Theta_1s*Sin(azimuth angle)

where: Theta_o , 1c and 1s are all constants (in degrees), azimuth is the position of the blade in degrees ( 0 degrees is directly downstream)

I'm new to field functions so I was wondering if anyone could help me with creating a field function for the rotation if say 1 time step = 1 degree of rotation
