Hi all
I have doubt and I would be appreciate someone can help me
At input piping for modeling an intersection I active SIF&Tees and I can study SIF o and SIF I at output (stress report) on the other hand software has another tool in Analysis menu for intersection SIF and I don’t understand what the deference between these two is.

Both use the same calculation. The tool under the Analysis menu is there so you can investigate SIF values without building a CAESAR II model.
