Unable to simulate interference fit using force (Hypermesh Optistruct)

Hi,

Is it possible to simulate interference fit using an axial force and not a imposed displacement on a two elements component initially separated?

The model with the imposed displacement works, the same model with different costrains and with the force is not convergent, which parameters should I change to make it works?

    Force driven problems can be trickier than imposed disp.

    You might wanna try adding some contact stabilization. (PARAM,EXPERTNL,CNTSTB or CNTSTB in the loadcase).

    It might help you.
