Quick connection of assembled parts

The idea is to define a unique Kinematic Coupling in between both hole surfaces previously adding the parameter orientation in cylindrical coordinates.

So something like this: CalculiX-Examples/Test/Joints at master · calculix/CalculiX-Examples · GitHub but with different DOFs ? And there’s just one coupling for each rivet (connecting both holes of the plates) ?

@ANYS

The absence of Springs or beams connecting both surfaces make it more suitable for automation.

The disadvantage is no results for bolts/rivets and no preload but it can be a good way to model simple connections as discussed here (or pinned joints).

So something like this:

Right. That hinge example trigered the idea.

@FEAnalyst

is no results for bolts/rivets

The ref node is in balance (It must) as it adds both sides reactions and has no interest but you can measure forces on just one side. On one side set of nodes or at the shell lip surface with section print.
