I'm trying to use a finite friction contact interface, but I'm getting the warning
"The analysis is invalid because finite contact interface is not supported for small displacement analysis."
This implies I should be using large displacement analysis... but that's greyed out so I can't select it.
What am I doing wrong?
Thanks!
From that, I'm doing two things wrong: I have an advanced spring (which I can get rid of), and fasteners (which are directly related to the finite friction I want to evaluate).
So currently it can't evaluate slippage of a bolt flange, at least not using fastener elements to create the preload?
I'm not sure finite friction is working properly yet.
Does someone have an update?

Beams, advanced springs, ground springs, fancy shells, weighted links ...
