Assembly with some weldments and some solids

I have some weldments of 1" and 1/2" round tube that are part of a larger assembly with other parts that are clamped onto those 1" tubes and am trying to make connections between the clamps and the tubes which are modeled as beams in the simulation.  It seems to lose the connection between the 2 types of parts when meshed and gives me the error that the model is not adequately restrained.  I tried solving with a soft spring and the weldments vanished after it ran.  I made it show me the max stress point and it had moved WAY off of the screen.


Is there a way to mix solid parts with a weldment in an assembly and run the analysis?


I've tried to change the weldment to solid parts but the wall thickness is .049 and .028 for the 1" and 1/2" respectively so the mesh fails on all of the tubes.


Any ideas?
