Bearing displacement in non-linear bearings

Hi,

I have created a model of a barrel vault (geometry + loads in Grasshopper). I encountered a problem while modeling the support displacements. The following boundary conditions apply:

The arch supports have a nonlinearity (failure in tension), so they can only transfer compressive forces.

When I apply the line displacement constraint (divided into x and z components according to the inclination of the supports), I get the error message that the line is not sufficiently supported.

My question is: How can I model a support displacement and, at the same time, a gap opening in the joint?

And one more question: I was told that it is possible to display the result distributions directly in the model – that would be great in my case, as it would allow me to estimate the compressive zone height directly! Does this option exist?

Thank you very much for answering!
