Hi,

I'm a student doing a final project using CFD. I'm currently new with CFX-post and i'm having difficulties searching for the aerodynamic moment value for my wing.
I have learned that the the torque value showed in the function calculator is using the (0,0,0) coordinate as the reference point, but my aerodynamic center isnt on the (0,0,0) coordinate. Is it possible to change the reference point for torque?
Changing the geometry to make the (0,0,0) as the aerodynamic center isnt an option for me because it means having to change the blocking/mesh which is quite complex. I have and still searching for this in the helps and tutorial documentation, but having no luck finding a solution.

Thanks

Create a new coord frame. Hit the icon that looks like a coord, and place it where you want, oriented how you want.

Then in the function calc, this coord frame will be available.
