So I have this Problem: I have an axisymmetrical body on which I have to perform CFD simulation to find out Drag coefficient and overall resistance at certain flow velocity.


Using Star CCM+, I made the sketch of the flow domain in XY plane and extruded it to 0.1m in Z direction and followed the steps required to get the solution.

Now, the drag force which I'm getting, is it the drag force of a whole body or just the strip of extruded distance ?

I'm confused so much any help will be appreciated : )
I'm attaching my sketch and my mesh screenshot to explain what I'm talking.


my model has a surface area of 17.2m2 and I'm getting a resistance of 310N at 4m/s
