Seperation Line

I am trying to model (using Fluent)flow past a prolate spheroid (3d Ellipse) to locate seperation lines at the aft end (masters dissertaion). I have tried both 2D and 3D models. The problem is I cannot seem to get results which show any seperation at all. I have tried all the turbulense models, wall functions etc. I have put a boundary layer in too, but to no avail. I have seen results proving it can be done using CFD but it will not work for me. I have tried all types of mesh on the spheroid surface, but I am restricted to unstructured mesh in the flow domain. Has anyone any idea how to solve this problem? All suggestions greatly appreciated. Thanks.
