MSC Marc - How do I glue elements with different mesh, edge to edge?

[Bainosa]

Hello
I don't know how to glue two differents bodies with different mesh, not only nodes to nodes but also edge to edge. I know that it's possible, because I have seen it.
I'm trying with the "contact table - glue - options"...
I have attached an image to see it better.
Thanks for your help

It looks like you put the coarse mesh as slave body, and fine mesh as master body. In the contact table, switch the slave/master bodies should work.
