Can you share the input file for reference ? So those are 2 GAPUNI elements (with spring-like symbols) attached to a common rigid body reference node ?

Regarding the compression-only constraint, it would be also helpful to have an option to invert its direction: [Tension-only constraint](https://prepomax.discourse.group/t/tension-only-constraint/1589)

Perhaps there could be a compression-only spring so that the user could apply it like Point Spring to selected nodes (although, currently Point Spring is grounded so I guess two-node springs would need to be added first).
