Guys i am trying to conduct a stress simulation on front end of bus body , but some beams dont get converted to line elements .I want to know following things:

  1. How should i simulate a welded joint on this beam . Please help. I created the front end structure using frame generator?
  2. Should perform this simulation using frame stress analyser or inventor nastran?
