Automating Constraint Equations Between Node Sets in Femap

[Danny123]

I'm working with a square model in Femap and need to link nodes on the upper horizontal edge to corresponding nodes on the lower edge using constraint equations. Each edge has 86 nodes, and currently I'm creating the equations manually, one by one for each node pair.

Is there a way to automate this process in Femap—perhaps using a script or a built-in tool—to generate constraint equations between matching node sets?

Any guidance or examples would be greatly appreciated!
