Dear all,
I'm working with Abaqus to perform FEM analysis on a polymeric product that consists of components fitted together but not constrained by bonding or locking systems, only through interlocking shapes of the components. I'm not sure what type of command to use to set this up. I tried simulating with Tie , but it significantly alters the simulation behavior compared to the real prototype I built. Could you help me out?

Yes, I have. The simulation was very long (like 8 hours) and then it aborted due to a convergence problem at the 43 steps. I had changed the value of Ia to solve the problem of attempts, but it wasn't work again. I also try the global contact interaction, but the situation is very similar. Probably I do some mistakes when I set them, I don't know.
I can not share the model for privacy's reasons. I can explain it in more detail . I use blocks of polymeric materials, which are in contacts. During some experimental tests we noticed that there was no sliding between the components, when they are subjected to a compressive force. For this reason I was choosen to use Tie as a constrain in Abaqus simulation. Moreover the value of the simulated deformation is the same of the real test, while the representation of the deformation is a little bit different. Do you think tie can be okay as constrain or not?
In addition, some parts of the blocks interpenetrate each other, not representing a real case, how can I overcome this problem?
