OK. Yea certainly get linear working first. I can’t think of any other reason displacement would be zero everywhere else though. Could you show a zoomed in deformed view of the displaced face and its transition to the undeformed area? I don’t know what to expect but maybe some clues in there.
It kind of looks like it hasn’t solved at all and the output is just the initial state. I wonder if PARDISO isn’t working or installed? Maybe don’t specify a solver or choose SPOOLES that should always be a fallback, I think.
You can also keep isolating the problem by removing things until it becomes correct. That includes deleting half the mesh repeatedly. That’s what I do for totally mysterious problems when I don’t have a clue.
