Structure with 2D and a 1D truss...

Hello all,

I am trying to implement this (see attachment).

I guess it should be relatively easy, and for sure lots of people know how to do it :).

After "spending" quite a lot of time, I decide to share my problem with you. I hope you can help me with that.

I guess the "problem" is with a boundary condition, or with the definition of a Pair there...

Thanks a lot in advance
