Fixtures I would try:
The edge you already selected "Use reference geometry" and allow rotation only for this edge.
You will have to create a plane on the bottom, and then make a Virtual wall (it's in contact sets)
I think you will also need to enable the "Large displacement" in Properties of this analysis.
Also Include Gravity in the -y direction.
You could this one in the Sim premium dynamics... but not sure if you have that one.
Hope this helps.
I've done it and now i'm waiting the analysis, but I think that it is what I want.
Thanks a lot,
could you translate it to English?
if you would send a Pack and Go i would try to setup this for you.
It might behoove you to use the surface parameters feature to find a few force points due to wind load and put it into motion. Motion is much better at moving bodies than structural FEA.
