*TIE for only 1 DoF

Maybe you could just use contact with some specific settings. For example, it seems to be possible to simulate no separation contact with a workaround: No separation contact

MPCs may also work, here’s a discussion about the use of them for modeling contact without actual contact algorithms:

Modeling surface contact with point-to-point linear contact

Hi, I’m following the book “Practical Finite Element Analysis for mechanical engineers”, and in section 14.7.2 I find an example where the base of a fitting is in contact with a plate and this contact is modeled as a point-to-point linear contact: [question] All the nodes of the fitting’s base have their own MPCs. The plate is not represented in the model, the MPC linear contacts are grounded. I’m using PreProMax for the FEM except for the MPCs. The CalculiX manual mentions in point 6.7.2 th…
