How many total links?

 

Contact sets might work for a few links

mated workpoints will allow more links, but restricts some of the DOF

Dynamic Simulation could be an option, but again - more than a few links is going to drag your machine to it's knees.

 

What is your true design intent.

The more DOF you can remove the easier for the computer to solve.

approx, 30 links per chain

A steel box with a chain on each corner connecting to a larger ring...actually does not need to move....i need to make 4 chains (each 30 links) .. each chain attaches to a corner on the steel box and then all 4 chains held together a the top on a large ring

That description sounds like all DOF can be removed.

Place workpoints where the insides of the links would be tangent (tangent constraint would be more complex than needed.

Constraint the workpoints.

Add constraints to origin workplanes between links to make them perpendicular to each other.

 

I would probably simplify by pattern Feature as body in single part rather than do these as individual parts.
