Skin Friction and Shockwave evaluate
 

Hello friends
I'm very confused to evaluate skin friction and shockwave parameter for my reverse combustion. I've simulate the design using Fluent 6.3.26 code and I want to optimize the design using that code.
The optimizing reference is from the pressure loss and the pressure loss can occur because of skin friction and shock wave inside.
Any body can help and explain me the step to see the skin friction and shockwave using Fluent 6.3.26?
Thanks a lot for your attention all
regards:)
