Ahmed body drag coefficient
 
For my Ahmed body analysis, I'm getting a value 0f 0.37 for the total drag coefficient instead of 0.25 I've checked everything so I'm guessing the mesh needs refinement. Could anyone give me a range of mesh values I could use for this problem?

What slant angle are you looking at? Have you checked the streamlines at the center line, you should see recirculating vortices behind the slant / base (or both).

Hi, can I know where you get the drag coefficient for 2.5? Is it from any journal or paper?
