Problem:

The program does not seem to be using the correct SIF for an elbow, why?

Solution:

SIF's are calculated based on selected Piping code.

Please see the following AutoPIPE help section:
Help > Contents> Contents Tab> Reference Information> Code Compliance Calculations> select a piping code (ex. B31.3 2016)> select SIF page where applicable. 

Things that may affect the output reported value:

1. Model Result Options settings enabled / disabled:

example:

Set SUS SIF =1 no bends

Single SIF at point

Set Sus/Occ SIF = 1

Set Sus/Occ = 0.75i

2.  "Override all other SIFs at this point" was enabled 

See AutoPIPE online help for Insert/Modify XtraData> Joint Type and User SIF> "Override all other SIFs at this point" 

3. Highest SIF at the node point.

The program is able to enter more than a single SIF at a node point, the program will only use / report the highest SIF value unless "Override all other SIFs at this point" has been enabled.
