SIF calculation

Hi dears,
Two question about SIF:

1- If on one element indicate SIF's & Tees and specify type of Tee, it is necessary enter manually SIF value or no?
2- If on one element indicate SIF's & Tees but leave Tee type blank, what value assume by CAESARR II?

1. no
2. 1.00 i.e. no SIF

Regards,
