having flexible elements displacements results reported in local element axes, provides a better way to quantify relative end displacements and avoids doing global to local axes transformation out of the software. Amount of end and intermediate displacements is important in flexible metal Hose and expansion joints design.
We added a flexible joint report in the 2023 release that report the displacement across flexible joints. We have fixed some issues with this report in the update due out in December, it sounds like this might be what you need.
