I don't know when the program will be up again,but I have some values to compare to.
If the program is evaluating 3-D flow in a 'free-flow' condition you should see Cd 0.04.That's from Hucho.
If it's evaluating for ground proximity flow you should see Cd 0.08.
If it's evaluating for 2-D flow in free flow,as in a wing section of strut,at the Reynolds number its at,and the thickness chord ratio,you should see a 'drag per unit length' value of 0.0861,Re:S.Goldstein.
There are no values for wings or struts in ground proximity.
