CoL, Lift force, CoD, Drag Force

Hello,
How do we find the coefficient of lift and drag of an object in CFX?
Also how do we find the total lift and drag forces?
Thanks!

Get the force on the surface in the output file or CFD-Post. Use the drag/lift coefficient equation to get CD or CL. Easy.

The question is how to do all these?

Do the CFX tutorials and all will become clear. Hopefully.
