thank you.
but could you explain me better the last two points?

1)reduce bend flexibility by calling it two flanged (1 for the expansion joint, 2 for the trunnion).

-in which points have i to activate the flag for "two flanged"?

2)calculate SIFs and input those, as well.

-do you mean calculate bend sif? how? and then in which point i have to impose it?

3) in the presure balanced EJ with the TEE (not the bend we are talikng now) have i to activate sif in the tee point? welded type?
