I think you'll have a hard time getting accurate displacement results with any method.

I recall once seeing a software package reviewed in Machine Design magazine that will Import results from Nastran and perform estimates of weld stresses. You might look around on the Machine Design web site to see if you can find it. If I run across this information, I'll reply with another note.
