FEMAP tutorials, videos, seminars, and resources


FEMAP 11.3 is the latest user-focused release of FEMAP containing many features and enhancements requested by our users worldwide. The latest version introduces new Draw/Erase functionality to dynamically choose entities to only "Draw" in the graphics window or "Erase" from the graphics window, which may be helpful when operating on a complex model. The new "Max Quads" option available when surface meshing will minimize the number of triangular elements created when meshing with quadrilateral elements. Selection of element faces for creation of loads or connection regions has been overhauled to offer new capabilities when using certain methods and allow use of multiple selection methods during the face selection process. On the Post-Processing side, the "Vector" Contour Style has been changed to "Arrow", which now uses the Contour output vector as a "base vector" to automatically determine the type of arrow(s), select additional output vector(s), and choose appropriate options for display. Finally, results in an ABAQUS ODB file may now be "attached" and used for post-processing.

Fatal errors and/or crazy stresses!

One of the most common topics for our technical support team is Connections (also known as linear contact). You’ve seen some great demos, you’ve got the perfect pin/clevis model and you found the “Automatic” button under the Connect menu. However, once your computer finally stops spinning, the analysis crashes. Sound familiar? The goal of this seminar is to break Connections down to the simple components and provide a basic understanding of how they work. That, combined with some suggested default settings should have you up-and-running for your next contact analysis.

We presented this online technical seminar on March 24th, 2016

 

There’s a lot of hard work that goes into getting a quality set of FEA results – geometry prep, meshing, materials, properties, boundary conditions, contact and analysis settings – and that’s if everything goes smoothly. But what do you do when the analysis results are finally ready? For some, that’s when the real work begins. Post processing (or just post as some call it) is the art of taking a mountain of data and turning it into something that is easy to present and easy to understand. A well-crafted combination of images and tabular data will tell a story about the structure and how it behaves under load.

Want to know about surface modeling and plate meshing with Femap 11.2.1? We presented an online technical seminar on September 10th, 2015.

This online seminar focuses on going from 3-D CAD to 2-D surfaces and then to a beautiful quad-dominant mesh. For most of us, this is where the rubber hits the road and our managers and clients wonder why it ain’t easier. We want to share with you how the new Femap v11.2.1 can make this process easier and get you that “quad” you have always deserved.

This seminar is intended for NX Nastran users that are interested in nonlinear analysis but aren't quite sure when, why and how to use it. This presentation will provide theory, implementation, and analysis examples of the following nonlinear topics:

  • Geometric Nonlinear (Contact and Buckling)
  • Material Nonlinear (Plasticity and Hyperelastic Materials)
  • Multi-Step Analyses (Contact with Bolt Preload, Residual Stress, Vibration of Stiffened Structures)
  • Gap Elements (Compression Only for Contact, Tension Only for Cables)

This technical seminar is intended for new engineers interested in modeling composites and experienced engineers who would like to get acquainted with the Femap interface. This seminar is intended to accompany a white paper and will provide you a starting background on composites.

The following topics are covered:

  • A little background on the mechanics of composites and how micromechanics can be leveraged to obtain composite material properties
  • 2D composite laminate modeling
    • Defining a material model, layup, property card and material angles
    • Symmetric vs. unymmetric laminate and why this is important
    • Results post processing
FULL OUTLINE:

This technical seminar will provide the background theory on normal modes (i.e., eigenvalue, natural frequency) analysis and then walk through the process for performing a vibration analysis from normal modes to modal frequency (sine sweep) to PSD to Direct Transient analysis.

As we know, covering this whole topic would take more than just an hour. We have some suggested readings and can point you toward additional resources for those that want more theory.

It has been a while since we have done our basic "Welcome to Femap" seminar and with the rollout of Femap v11.1.2 with NX Nastran v9.1, it was time. This seminar covers how we get the most from Femap in our modeling efforts. It covers the classics of working with Panes, Model Organization and Visualization, Setting Preferences for Ease-of-Use and Working with Toolbars. We also do some basic model building and demonstrate some of our favorite tips and tricks to make your analysis speed along.

This is an all-level technical seminar from which we hope new and advanced users will be able to take away something useful.
