to find drag coefficient of an ogival body

Hi ! I want to find the drag coeff of an ogival shape. I have made the grid in fluent with press inlet boundary condition far ahead of the ogival body and press outlet at the end of 2D ogive. The mach # is 0.6 in standard atmosphere, the solution doesn't converge after a lot of iterations. i have changed the press inlet condition to press far field but the problem remains there. the shape of the domain is just like the alphabet 'D' with ogival shape attached to outlet boundary from behind.
If I give supersonic M# the solution is fine, I see perhaps press outlet b.c is creating problem....what pressure should I give at press outlet as i see that this is the only b.c condition for outlet available for compressible flows |

Hi All
Any ideas if std press is given at press inlet or press far field ahead of the body , what press to give at press outlet attached to the rear of the body for compressible flows....... |
