Hi.

First of all I would like to refer to my drawing. Imagine this case:

A float made of 316SS is connected to a wire, which connected to the bottom. The scenario is under water. I don't really care about the wire nor the bottom-connector, I am only looking at the float.
I would like to do following simulations: Static, Buckling and fatique.
My question is: How do I connect the float, so it is realistic? I tried different type of fixtures, for instance, Fixed geometry at the bottom, but that doesn't give me realistic results. Can anyone help me in which fixture type I should use to get realistic results?

Thanks on forehand.

Br,

Andreas
