Topic: Spring "Coupling / Interface" Between 2 Nodes

Hi all

i would like to ask if it is somehow possible to define a spring just between 2 nodes and give this spring a nonlinear behaviour (similar to a support-spring).

this option is more or less available for lines and surfaces in the form of interface materials.

However to explicitly define a nonlinear spring between two nodes of my choosing would be a bit better in my case.

Thanks in advance !
