hello @peteroznewman

I did a static calculation without contact at the top by applying a force at the top, I found a deformation of 49mm upwards which is not real so to limit the displacement I used the contact at the top while respecting a distance of 20mm but when I look at the deformation after the use of contact I find 2mm which is not real either my model is supposed to move up to 20mm 
can someone tell me where i made the mistake. i used a standard rigid contact.
can you tell me how I can limit my displacement.
I work on ansys apdl

Hi,

 

Can you please detail the setup/ problem that you are trying to replicate?

Hi @AshishKhemka @peteroznewman

I created the contact between the top surface of the mechanism and the circular surface, I put an offset contact because I want to limit the movement of my mechanism to 20mm.
The problem is that it does not take into account the contact.

as you can see on the picture the mechanism crosses the circular surface so it doesn't take into account the shifted contact, it is supposed to move just 20mm without crossing the circular surface
