Dear all,

I had a Doubt of how the SIF factors are calculated by the Softwares like Caeser or Triflex, As I know the software calcluates itself based on the fittings we select.
I had this doubt because when I checked with the Output results it just shows value as 1 for Butt weld Concentric reducer. actually It should be Max. 2 as from the Code B31.8. Could anyone tell how ur working with this SIF at your projects using Softwares like this. Do u calculate manually for all fittings and feed it?
