Connect ChElementBeamEuler to ground via a spring

[Anders Sneckenborg]

Hi,

I am just beginning to use pychrono and I am trying to learn basic things.

I have managed to create a beam made with ChElementBeamEuler. 

I then tried to connect it to ground via a ChLinkTSDA with no success.

After that I noticed  fea.ChElementSpring and tried to use that but again I didn't succeed. I realize that the nodes for ChElementSpring should be of ChNodeFEAxyz type but the nodes used to create the beam is ChNodeFEAxyzrot. 

How can I connect the beam to grund via a spring?
