Change contact pair to identity pair keeping resulting position

Hi,

I have a scenario I don't manage to solve. For example:

Step 1: A cylinder is sliding inside a upper block and applies a load to the lower bloc. It has a resulting displacement and the lower bloc is in a stress state.

Step 2: the cylinder is clamped at the resulting position to the upper block and the stress state of the lower block induce a load to the upper block thru the cylinder.

I tried to:

  • use two stationnary steps

  • in the second step change the contact pair to identity pair and remove the initial load

    but it does not work. It behaves as if the identity pair was applied to the initial position, no load is applied to the upper block.

    Any idea ? I joined files to detail the problem.

    Thanks!...
