How to model a tensioned cable in Inventor Simulation?
(OP)
Hello,
I am modeling a structure that will consist of an I-Beam with a post at its center and two cables that span from the ends of the I-Beam to the end of the center post (creating a triangle).
I was originally going to add a standard force to each mounting surface of the cables, but that would put the cables in compression. Also, if I don't model the cables themselves (just add forces where the cables mount) then I won't get an increasing force as the "cables" are stretched during loading.
Any advice would be greatly appreciated.

I think more information is needed.
I would load the assembly the same way it will be loaded in the real world.

If your loading changes and they go into compression then you need to delete them from the model.
IF your program is suffciently clever you can get the same effect by replacing each cable with a pair of rods connected by 3 hinges. This will collapse under compression but work under tension.
The stiffness of a cable is much less than that of the same diameter rod, you need to account for that.
If your cables are pretensioned then things are more complicated.
