Coupling membrane and rigid body

SOFiSTiK
1

This is a simple question for a new Sofistik user, but I am wondering if there is a way to do surface to surface contact interaction in Sofistik.

I am specifically trying to couple a rigid body to a pretensioned membrane structure so the tension of the membrane applies a force to the rigid body.

Let me know if anyone can help with this coupling problem.

Sofimshc -> SARS
Either a fixed or a spring connection are possible.

thanks for the help,
Is it possible to do these fixed and spring connections between geometries when designing in Rhino/Grasshopper?

The coupling of two structural areas is not directly implemented within Grasshopper. But you can try to add a custom CADINP Code that includes the SARS command.
