I've got a rather large assembly that I'm trying to do thermal expansion analysis on, and it's basically 3 parts repeated many times.   I've got the material properties defined in the individual part files, but simulation keeps giving me an error that the bodies don't have materials (because I haven't defined the 30+ bodies WITHIN the study).

Is there anyway to force simultion to use the material definition from the part files, rather than having to define them all in the simulation itself?
