school assignment. cd to high.
 

i am an undergraduate student, and i am really new at the ansys fluent, but i have to perform a aerodynamics simulation of car, and take the respective CD, drag coefficient, for an school assignment, i set the k-epsilon model, with 40 m/s velocity, the problem is that i got a result completely impossible, it was about 7000000 of drag coefficient, i set all the other settings as a default, someone can help me to figure out what i set wrong?

Check that the reference area is correct (via Setup > Reference Values > Area). This area will probably correspond to the cross section of your car (depends on how you have defined your drag coefficient).
