I am interested in obtaining the forces Fl,Fd,Fmy where Fl=lift force Fd=Drag force and Fmy=Moment about y-axis I know that fluent gives the Cd,Cm and Cl, but I will like if anyone knows how to obtain the forces. Thanks to all

I'm assuming you're talking about when you monitor forces (when you Report->Forces it lists the force and the coefficient).

If you set RHOref=2, Vref=1, Aref=1 and Lref=1 in the reference values window then you'll get forces (check your units though!)

Remember:

F=(1/2)*RHOref*Vref^2*Aref*Coef and

M=(1/2)*RHOref*Vref^2*Aref*Lref*Coef

So by setting the values I gave earlier, you've simplified the formulas to:

F=Coef and

M=Coef

But like I said, double check your units.

Hope this helps, and good luck, Jason

Thanks Jason
