I have a space truss assembly that is supported by tension cables.  The device is similar to a construction crane, one end is supprted by a rigid structure and the free end is supported by tension cables.  I understand that the cables themselves will likily reposnd in a non-linear manner and can't really be modeled with solidworks simulation.  However, I'm trying to run a beam model simulation to determine the reactions at the connection points.

I have tried creating a rigid bar member bewteen the points.  But since there are multiple points and both latetrally and vertial acting forces, the displacements run coming out in the unbelievable range this way.

Anyone have an idea on a wwork around this issue??
