Noorsyam,

Thanks for your reply.

Iam taking about vector F1 in CAESAR-II. not the force F.

what i understand you are saying, apply flow direction force and reverse flow force individually and check the stresses. Is my understanding is correct.


If you check the hammer spectrum analysis Caesar-ii example they did the combination also. Pls check once.

if the fluid is not in single phase, i think forces cannot be canceled then that case , going with case 2 is ok or not
