Buried Pipe: How to add mechanical coupling

Hello,

I've a buried piping system. I want to add a mechanical coupling between two anchor blocks, so can any one please tell me how to add this mechanical coupling in Caesar II, I did it in past but I forgot now how to do it, and I remember that I have to specify the gap in mm inside the coupling. Thanks in advance

Regards

AFTER the system is "buried" in C2, break the pipe at the location of the coupling. For example, break 90-100 by adding node 95. This will create two element: 90-95 & 95-100. Change 95-100 to 96-100. Now you can model your coupling as restraints between 95 and 96 - restraint at 95 and a CNODE 96. CNODE is the C2 "connecting node"; you are defining a restraint between two nodes rather than typically between the node and "earth". (I don't mean earth as in soil but earth as in the planet - you can't move earth.) Consider all 6 degrees of freedom when defining these restraints with CNodes.
