Assuming the tied parts are not rigid, I suggest you try *CONTACT_TIED_SURFACE_TO_SURFACE_CONSTRAINED_OFFSET . That will make the tied contact constraint-based rather than penalty-based. Check your segment sets 3 and 4 to confirm those segments lie only on the surfaces you want to be tied. If you get warnings about untied nodes, boost SAST and SBST to -1.2 and if that doesn't work, as an experiment, try using positive values of 1.2. Report back your findings.
