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.
