Who can explain to me the function of activating the option of Displacement Convergence

[peteroznewman]

The default convergence tolerance for displacement is 0.5% which is sufficient for most models. It means that iteration will stop when the change in displacement from the last iteration to the current iteration is less than 0.5%.
An example when 0.5% is inadequate is a shrink fit model where a very small change in displacement can have a large effect on stress. In that kind of model, use a convergence tolerance of 0.01%
