NX Advanced FEM (Version NX 5) © UGS Corp. 2007. All rights reserved. UGS PLM Software Aims f There are 225 slides in this file, it is NOT the expectation that you show all of them to the prospect/customer f The aim here is to provide a deck of slides that you can choose to “pick and mix” from to show a workflow or solution that is appropriate to your requirements f These slides describe the “Core” functionality. I have skipped some icons/functions as they are only applicable for one of the add-on applications. f These can be used as the build up for a presentation on one of the add-on applications like Laminates, Response Simulation, Thermal, Flow etc f As these slides are all built to a consistent style, doing a “pick and mix” will still result in a clean looking presentation f Please note that after the Solver Language Environment slides, everything is NX Nastran specific f Please provide any enhancements or suggestions to Guy.Wills@Siemens.com (+44 1462 44 5029) Slides 2 – 6 are not
