This is a model for a brick masonry wall.
I used contact 174 and target 170 elements.
I assigned from ''contact wizard ''.
Node 25042 seems not to be properly constrained: you should highlight this node, verify to which elements it belongs, and how these elements are connected to one another.
You have a plane contact area. Sliding is permitted and is not restrained by any constraint. This must be the problem.
A grateful thank you to both of you
