Moving Coordinate Frames in Post
 

I am fairly new to CFX and CFD post. I have data from a past simulation that looked at a pitching body. I would like to calculate the pitching moment about a centre that is on the body but is moving; ie is not at the centre of rotation. I know that I can create a new static frame in CFD post that is in the right location and orientation, and then use the calculator to get the torque I want about that frame. However this requires me to manually update the frame every time step, which is cumbersome. Is there a way to automate this using expressions?
