Contact problem with overlapping mesh results

[Calc_em]

We had a discussion about interference fit modeling here:

Modeling interference fit (shrink fit)

Hi, does CalculiX have an option to model interference fit (shrink fit / press fit) in contact? So that I can place two parts with initial interference and it will be resolved by the solver with stress and strain generation (unlike slave adjustment in tie constraint). I haven’t seen any keyword for that but I came across some websites mentioning presfit option, however I’m not sure how to use it. Especially that I submit the job via preprocessor and I don’t use any commands for solver. Is there…
