may this is not a must in CCX, as many FE with the same capabilities. i try reproduced [this problem](https://github.com/calculix/CalculiX-Examples/blob/master/Contact/Shell0/README.md) using manually defined MPC (6dofs is constrained) based on nearest distance. it’s run, solved and display result as expected.
