11th Bi-Annual European LS-DYNA Conference 2017 – Salzburg, Austria, May 9-11

If you are a LS-DYNA user or interested in learning more about ‘DYNA, then attending this conference in Salzburg would provide in-depth and detailed information on the reality of using the world’s most capable non-linear multi-physics FEA tool. What I find most valuable is the ability to discuss detailed modeling strategies with fellow experts and get the up-front messy details about what works and what doesn’t.

The most recent conference that I attended in Bamberg, Germany in October (14th German LS-DYNA Forum) had around 350 attendees in which 300+ were engineers that actually drove LS-DYNA. This is quite amazing since most technical conferences tend to attract a lot of salespeople that would rather advocate software over hard-earned mechanics knowledge.

Like I mentioned, if you want to sharpen up your simulation skill set, then get out of your cubical and come to Salzburg this coming May. I will promise you that you will learn a ton of new information and have some of the best networking opportunities in the world with your fellow simulation engineers.

Predictive Engineering Opens New Office in Munich Germany

Predictive Engineering announces the opening of its new office in Munich, Germany. Situated in central Europe, Munich offers the ability to quickly communicate with continent-based clients within the same time zone. An advantage for Predictive and its sister company Applied CAx is that Munich is also the headquarters for Siemens, a worldwide provider of engineering equipments, systems and PLM Software. If your work brings you to Munich, please lets us know and we can arrange a meeting. 

Mit freundlichen Grüßen

Doing a bit of Research on Brazing of Ceramics to Metals

I was doing a bit of online research on the FEA modeling of the brazing process. We have a client making high-tech ceramic to metal fixtures. The ceramic is joined to the metal substrate via a brazing process. Upon cooling to room temperature and depending upon the geometry and material selection, residual stresses can develop to the point of causing failure of the components. It is tricky and we have embarked on a modeling project to quantify the mechanical response of these fixtures. Well, back to the story line. During this search I stumbled across this old paper that I had co-authored with a client. The paper is titled "CFD Analysis of Automatic Test Equipment." It was a trek down memory lane to see these old CFD models and realize that we have been doing CFD consulting services for more than 20+ years. It was some sweet work on large test equipment that was cooled using both water and air loops. The paper shows how we used CFD global (machine) to local modeling (board-level) to arrive at accurately predicting chip junction temperatures. Looking back, yes the models were crude and the graphics a bit funky but what can we say - it was 2002 and it worked!
