bia, it seems I've given you insufficient information, apologies. I meant to say that the drag force should be expressed as
D=\frac{1}{2} C_D \rho U_{\infty} ^2 A ,
where A is the area of the...

You need to specify the reference values for the calculation of the drag coefficient. Remember,
D = \frac{1}{2} C_D \rho U_{\infty}^2,
where you need to provide the wanted flow variables. Fluent...
