[CFD-Post] Calculating aircraft moments

Just need a sanity check for calculating an aircraft moments in CFD-Post.

I've simulated an aircraft half-model since the port starboard are symmetrical. The global co-ord frame is at some arbitary upstream of the aircraft on the symmetry plane. I made a local co-ord frame at the required position on the aircraft. For both co-ord frames:

x is postive aftwards
y is positive to starboard
z is positive upwards

So I've used the expression:

torque_y_Coordinate Frame 1@()Aircraft

for the pitching moment. Likewise torque_x_ for rolling and torque_z_ for yawing moments.
