At piping branch point(Tee)when user defined SIF(i)&SIF(o) are used in the analysis using CAESAR-II,

1.It is mandatory to define branch type at one of the element (out of three intersecting elements), in case design Code uses EFFECTIVE SECTION MODULUS for branch. For example ASME B31.3

2.If design code uses EXACT SECTION MODULUS for branch in the calculation, then user should not enter branch type at any element (three intersecting elements). Only user need to enter values of SIF(i)& SIF(o)in all three intersecting elements.

Intergraph members are requested to confirm above understading. Kindly correct it in case above information does not hold true.
