cg in Fluent
 

Hi,

I want to obtain the roll, pitching, and yaw moment coefficient for the whole airplane (fuselage, wing and tail).

I need to set the cg (center of gravity) to get these values, but I don't know how. Anybody knows about this?

Another question. When we simulate a wing and set the aerodynamics center in report --> force. This moment is calculated relative to cp (center of pressure)? Does Fluent calculate the cp automatically based on the pressure distribution?

Thanks in advance.

Fluent does not calculate the Xcp directly. You can calculate it from Cm and Cn which are calculated.
