    Sliding contacts resulting in excessive displacement

      This jack is a tube inside a tube sliding design with a hydraulic cylinder inside to extend it.

      I fixed a pad on the side of the tube where it welds to the machine.

      All loads were applied at the foot pin.

      I meshed with the parts touching - edge on surface, then defined a Bonded contact on one edge and a no penetration contact on the other.

      I can get the analysis to run, but the assumption that one edge is Bonded is wrong.

      If I mesh with parts not touching, and define No Penetration contacts for both edges, it fails, even with some rigid bar Links connecting to the top to hold it.

      How do I get both edges to slide on a surface?
