Despite continuous improvements in software and hardware, there’s still need for idealization and engineering judgement when it comes to creating effective FEA models. Yes, with today’s computational horsepower it’s possible to pull in a complex CAD assembly, put a fine tet-mesh on it, set up automatic connections and let it spin for a few hours. But your productivity might not be the best and it also puts you in a tight position for performing checks or sensitivity analyses or performing what-if scenarios. And most likely, you don’t want to lug around a million node model - debugging, run times, and data management all become quite painful with models of that size.

A more elegant approach is to follow the lead of FEA veterans and use a global-local modeling or breakout modeling approach. Global-local modeling takes a very large assembly and reduces it to something that is quick and easy to optimize. Another way to view global-local modeling is like an advanced form of FE symmetry – if it works for your simulation it is like free money.

This seminar covers a variety of FEMAP and NX Nastran topics relevant to global-local modeling from generating interface loads with freebody diagrams to extracting sub-sections of your model with the Select Toolbar.

This quick tutorial covers the challenge of an axisymmetric model with contact. We start from the basics and then show an example courtesy of one of our clients. We came up with this rather complex challenge and to solve it we started simply with a 2D plate with a hole then we moved to something axisymmetric. At the very end we were able to check it against our real model.

This five-minute-tutorial provides an introduction to the world of composite laminate modeling. From creating a 2D orthotropic material to using APIs to assist in post processing, this jam-packed tutorial covers our standard workflow. In fact it’s so jam packed, we had to add a couple extra minutes!

OUTLINE:

  • Composite Material (2D Orthotropic) – UD Carbon Fiber
  • 9-ply Symmetric Layup (45°/-45°/0°/90°/0°/90°/0°/-45°/45°)
  • Laminate Property with Hill Failure Theory
  • Meshing – just like standard plate elements
  • Material Orientation – the reference angle
  • Post Processing – deflection, stress and failure indices

Sometimes it’s the simple things that make life easier and so, this webinar provides a grab-bag of tips, tricks and new features in FEMAP v11.4. Plus we look at the top 10 things we love about FEMAP.

This seminar should provide useful for everybody from new users to FEMAP veterans. We presented this live online seminar on Thursday, August 3, 2017

In this technical seminar, we look at how to extract weld line stresses and forces. Our assumption is that a post-weld heat treatment has been performed and that the residual stress state in the weld zone is quite low.

To illustrate this importance, we provide an FEA simulation of how residual stresses develop in a welded T-joint as it cools down to room temperature. Please don’t get your hopes up that this seminar will be the definitive work on weld modeling and analysis, the topic is just too broad to cover in an hour or even in a week of lectures. What we will show is our best practices at Predictive Engineering from ASME to Blodgett's.
