Resistant Coefficient (Ct)

I am a student from Malaysia, doing a research about calculating Trimaran resistance in calm water using ANSYS CFX , so, I want to know how I can get the resistance coefficient for the ship, detail of the setup is:
inlet; boundary details,subsonic, normal speed,22m/s, medium intensity-5%
outlet; boundary detail, subsonic, static pressure, 0 pa
wall; the hull itself, no slip wall
symmetry; the bottom, side and top of domain, set with free slip wall
domain; fluid domain,water,continuous solid,reference pressure=0 pa ,stationary
Global initialisation; domain initialisation, cartesian, automatic with value, U=22m/s,V=0m/s and W=0m/s, medium intensity-5%
I am new with ANSYS, and this setup is based from a basic tutorial I found in internet, if there is any error or suggestion, please feel free to tell me, below is the link for the image of my work...

I have moved this thread to a new thread. Please do not hijack other threads.
Mesh motion - do the tutorial examples in CFX on mesh motion.
Resistance - Use the force_x/y/z functions to get the force on the body and calculate resistance coefficient from there.
