Moment coefficient of moving airfoil

Hi,
I'm modelling an airfoil undergoing sinusoidal pitching and plunging motion, using tabulated6DOF motion. I have a centre of rotation of my airfoil (x = chord length/3) and would like to calculate the moment around this point for the duration of my simulation. However, in the 'ForceCoeffs' file, I can only specify a single point for the Centre of Rotation (CoR). My centre of rotation will be moving up and down with the airfoil so the moment coefficients I get are around the wrong (fixed) point. I can see two ways to solve this: 1) Being able to specify my centre of rotation as moving or 2) Being able to find the aerodynamic centre of the airfoil throughout its motion. I can then use the lift and drag forces in a moment equation to find the moment around my (x = chord length/3) point. Does anyone know how to do these? Thanks, Calum |
