I'm trying to get my head around weldments and simulation.  I have a simple test piece, a three body weldment with two different types of weld, which I want to run a simulation on.  SW knows about the joints but wants me to add bonded contact sets between the parts.  This seems unrealistic to me since the bonds are between the welds and the parts, not between the parts.

I usually do this type of construction as an assembly with bonded contacts but there seems to be some benefit in using the weldment facility and the simulations should be more representative of real world conditions.  The file is attached - it is only a test piece, I would want to do this on much more complex fabrications.  Can anybody point me in the right direction?
