This file contains two examples of motion declatation, rotational and linear:
1. Rotational motion

!q[rad/s] = 0 + 4.88795 * cos(280.05912 * t + 0.1)
-dof.angular.pitch.rate.motion rad 0 cos 4.88795 280.05912 0.1
!declare origin of motion point (the rotation declared above will performed around the following coordinates)
-dof.origin.of.motion 0.25 0 0
2. Linear motion emulating angle of attack of 1.25 degrees (note: cl/cd log items are calculated relative to the direction defined by "alpha" directive):
