moment defining
hello everyone：
I want to know how Fluent define the Moment Coefficient, Was it defined as: cm=M/(0.5*density*v*v)? or someelse form. thanks a lot! 
cm=M/(0.5*density*area*length*V*V), all taken from reference values.

Duri,thanks for your attention
now,I have known that cm=M/(0.5*density*area*length*V*V), and all taken from reference values. I also use Fluent Function compute_force_and_moment to get the moment,then i used the moment to get cm, I found that this cm was diffenent from the MonitorsForceCM, Could you tell me why? 
It will be same. Check moment origin, axis etc.

I think i have misused this function, could you give me a UDF that contains this function, thank you very much!
