Dear Sirs,

I have a problem with CAESAR II. The software does not accept user defined SIF for code BS7159 and UKOOA. Even by changing input parameters such as pad thickness and FTG Ro for equal tee, SIF does not change.
In my case, equal tee is over-stress because of hoop stress. Even with increasing pad thickness I can't solve the problem. (It should be mentioned that tee is fabricated tee).
I know in BS7159 for fabricated tee, thickness used for calculations(tM)is pipe thickness. How can I model the tee to overcome tee over-stressing?

Please guide me.

I don't see the problem. I can change geomety input to change SIF, or overwrite the SIF, and the expected results show up.

Could you send me your job, so I can take a look at it, please?
