I think you can contact Mr. Tony Paulin, they develop PCLGold as a stress tool more linked to FEA.
There is a webinar available at
http://paulin.com/Library/Webinars/2011_...resWebinar.htmlAs a personal opinion, I think that a FEA analysis is well fitted with ASME VIII Div2 or ASME III but the Piping codes simplified too much the concepts, however remaining on the conservative side (that's why the improvements as Appendix P failed, isn't it?)
