LS-DYNA: Observations on Implicit Analysis

This is the 1st in a series of informal articles about one engineer’s usage of LS-DYNA to solve a variety of non-crash simulation problems. The second was on LS-DYNA: Observations on Composite Modeling, the third was LS-DYNA: Observations on Explicit Meshing, and the fourth was LS-DYNA: Observations on Material Modeling

I’m doing more and more implicit work with LS-DYNA and would like to share some of my observations on its improvement over the last couple of years. You might be surprised how far Mortar Contact and linear dynamics (e.g., PSD and general NVH) have come. This article provides a quick little overview of what is happening with LS-DYNA implicit, some tips and tricks we have learned along the way, and resources that are available to sharpen up your skill set.

10th European LS-DYNA Conference, Wurzburg, Germany

This biennial LS-DYNA conference was held in Würzburg, Germany and was hosted by DYNAmore of Germany. Predictive Engineering was represented by Adrian Jensen and George Laird where we presented our new LS-DYNA MPP Program Manager interface. Key topics of interest were the new CFD capabilities within LS-DYNA, extensive code improvements toward increased scalablity (MPP and hybrid SMP/MPP) and advanced composites modeling. Besides over 170 papers (see DYNALook for a digital archive of the papers) concurrent workshops were given on implicit, CFD, composites, dummy positioning, etc.

As with all LS-DYNA conferences, the social activities were outstanding with beer gardens, gala dinners and lots of time to discuss engineering simulation with the over 450 attendees. If you are using LS-DYNA or interested in nonlinear, transient analysis, the LS-DYNA conferences are great venues to network, learn new skills or just expand your horizons.

Femap and LS-DYNA: Rocket Science Made Easy

This presentation was made at last year's Femap Symposium in Atlanta but it is very relevant to anyone interested in learning about how Femap works with LS-DYNA. The presentation is titled: Femap and LS-DYNA: Rocket Science Made Easy  If you would like to see the videos used in this presentation, click on the graphic below and it'll take you to our YouTube video. The next Symposium for us, will be in Seattle. If you would like to register for this Femap and NX Nastran Symposium, just click on the prior highlighted text. We plan on having Mark Sherman out from the Femap Development Team and the usual host of characters to present hard-core technical information on how you can grow and leverage your Femap and NX Nastran skills. Plus, it should be some killer networking and we'll have a no-host bar at the end of the day.
