Good day

I have been tasked to determine and supply the piping loads acting at the nozzle to shell junction of a pressure vessel.
Initially, I used the connecting node method to extract these loads, however these loads seem excessive.
Caesar II has an option which allows the user to input the translational and rotational stiffness of a restraint.

Question:
1. How does one go about using this option to input the stiffnesses of the nozzle/shell junction of a pressure vessel in Caesar II?
2. Where can these stiffnesses be obtained from?
3. How many are required? translational and rotational.

please advise.

thank you
