How to determine the Drag Coefficient using POST?
Hi Im new to CFD, currently trying to carry out a wind tunnel analysis on flow around a vehicle, I have went through the solver, but running into problem determining the Drag Coefficient for the vehicle.
The velocity is aligned to the x-axis, so In CFX-Post is it appropriate to plot "Force X" on the Vehicle body and use the Max value and apply it to find the Drag Coefficient as follow:
Cd = force_x()@vehicle_Surface / (0.5*Rho*U^2*A)
Is this the correct method? please advice?
