modelling a 3Dspring

[maxens]

Hi everyone,

I would like to create a beam (beam1) bearing on two simple supports (ok) and then added a perpendicular beam named beam2 at mid span on beam1 (ok).

My problem is that I would like to create a spring in every direction, 3D, using CBUSH (is that the best way ?) but I don't succeed. I create a element between beam1 and beam2, defined the cbush properties but I quikly figure out that the analysis is not correct...

Any ideas to help me?

Thanks a lot

Maxime
