I have tried Application example of Snap-Fit Buckle for Discovery Live and it seems to me, that the result for stress is not correct. When I used different boundary condition like force, the result was ok, but with displacement boundary condition it is not, see in the picture. But I do not know the force. So how can I solve this case in Discovery Live?
Thanks for your help in advance.

To find the force you could create a calculator measuring the Reaction Resultant on the face. For the given displacement in the model it reported about 3.8 N at the default fidelity setting. Click More when defining the calculator and expand the Result menu.

I have tried your proposal. But when I used force 3.8N there was no the same value of max. deformation in comparison with displacement boundary condition. In case of force boundary condition the stress and deformation distribution looks as I would expect, but the value of deformation is different?
So which results are correct? Why when I use the displacement boudary conditions the stress distribution is not correct?
At the first sight this case looks like a perfect case for DL, but I think maybe it is not. If it is not possible to solve it by displacement BL, the simplicity of DL is lost then.
