FEMAP tutorials, videos, seminars, and resources

We have condensed down our best modeling practices and recommendations into this 50 minute seminar. It covers how we verify our models for consulting clients and provides a template on how someone new to FEA can proceed safely in creating and analyzing a structure.

Many of our practices may sound routine and commonplace, but over the years we have not found it to be the case in the industrial FEA workplace. Although we may not cover every check known to FEA kind we believe that if one follows the guidelines given in this seminar one can avoid 95% of the problems that we have encountered within our own modeling work and that we have seen via technical support assistance.

There are so many options within the Femap Analysis Manager and for the majority of analyses, there's no need to mess with them. But as engineers, we always want to ask "What does this do? How does it work? Why is this here?"

For me, the Model Check page of the analysis manager stirred these questions. I finally stopped automatically clicking the "Next" button and started to investigate the Groundcheck options.

In this technical seminar we will explore the Groundcheck options with some example models to determine what these options do and when they are useful. In addition to the Groundcheck overview, I will present a "fluffy" API that uses the GFXArrow object to assist in making attractive Femap graphics.

This seminar is on multi-point constraints or R-elements (e.g., RBE2 and RBE3) and the CBUSH.

These elegantly formulated elements will be discussed from a theoretical background and then demonstrated through a number of examples.  The goal of this seminar is to provide the Nastran analyst with a comfortable foundation in how these elements can be used accurately and efficiently.  It has been our experience that in the modeling of bolted connections or non-structural discrete masses or just providing a flexible connection between adjacent parts, the right choice of connection element can be very important in the downstream results interpolation.

This mini-workshop covers the basics on buckling theory and shows how it is treated using FEA methods. Euler’s buckling equation is presented and compared to the eigenvalue linear buckling technique for a simple column. A geometric nonlinear analysis is then done for the beam and compared to theory and linear buckling. A more complex example is then presented showing how the buckled mode shape can be used to initiate nonlinear buckling in a perfect cylinder. A discussion is also provided about the pros and cons of linear buckling versus nonlinear buckling analysis. The workshop closes showing how LS-DYNA handles nonlinear buckling and the initiation of buckling in perfect geometry using the *PERTUBATION function.

This webinar is a great place for a new Femap user to begin. It covers the basic model-building workflow: Geometry, Material, Property, Mesh Sizing, Meshing, Loads, Constraints and Analysis. Although the model-building workflow is going to be the same for all FE models, there are different ways to work through it within Femap. The webinar covers the workflow through the File Menus, the Model Tree and the Selector. A quick demonstration of a guest API is provided as well.

A bit of a dry seminar on normal modes analysis. A graduate seminar condensed down to just a few pivotal concepts.  Normal modes or Eigenvalue analysis is the cornerstone of the majority of dynamics work and is the foundation for PSD or modal frequency analysis or noise vibration harshness (NVH) studies.  If you know how normal modes work - you are well on your way to understanding all dynamic behavior.

This webinar discusses the new visibility options within Femap v10.3.1 and some misc. topics relating to hex meshing and using the API interface. We demonstrate three new API's that:
(i) create PSD RMS von Mises stresses for plate and solid elements from the standard NX Nastran PSD RMS component stresses;
(ii) map multiple load cases from an Excel spreadsheet into your Femap model with titles, variable coordinate systems and all six load directions; and
(iii) replicate the Patran "Plot Erase All" command with single keystroke.
