thanks for your help. I tried *CONTACT_TIED_SURFACE_TO_SURFACE_CONSTRAINED_OFFSET with SAST and SBST to -1.2 and the result looked like this:
But setting SAST and SBST to +1.2 worked fine:
The problem in this case is, that the Shell Nodes are tied twice, with the part on top and the part below the shell. Therefore the warning, that the nodes are tied on two interfaces occurs. But the result looks fine.
I used SMD and LS-Run 2022 R2 with LS-Prepost V4.9.12-16Dec2022.
Thanks and best wishes
