Hey!

I ran a CFD simulation to study the forces acting on the body and fins at 4AOA and some roll angle. where fins are named as f1, f2, f3, f4.
I found the difference in force values for f1 surface from fluent to cfd post. Can anyone explain why is it so??

Forces in y directions from fluent:


Force in CFD Post after exporting:



Also I exported the csv files sand summed the forces in y-direction to check it was coming to be -45.4809 for f1.

Thanks

What does the vector (0 0 1) represent?

Sorry! I pasted the wrong screenshot. I have updated the image now.

Please check reference values. These are important for post processing. 

Please go through help for reference values.

In the fluent I have stated the reference values that I needed. Do I have to mention this again in post? 

[Rob]

What values are you expecting?
