I got it to work using plane strain elements. Most interesting to me was that I have to use the following contact parameters that I evolved from this post ([Convergence issue in 2D contact problem](https://calculix.discourse.group/t/convergence-issue-in-2d-contact-problem/292)):

```auto
** --------- Contact ---------

*SURFACE INTERACTION,NAME=DEFAULT
*SURFACE BEHAVIOR,PRESSURE-OVERCLOSURE=LINEAR
1000000000,0.1,0.01
*friction
0.3,1000000

```
