Trip & Training Recap: Houston, Lockheed Martin, and BBQ

BBQ in HoustonThe weather was hot and muggy as Tropical Storm Cindy floated past Houston but fortunately, the power stayed on and the FEMAP and NX Nastran training class went off without a hitch. Ten analysts from Lockheed Martin’s Orion program participated in the training and worked through real-world examples from CAD geometry to full Global-Local models.

The engineers have honed their Nastran skills working on the Orion Multi-Purpose Crew Vehicle and now have the FEMAP pre and post processing techniques to liberate them from the dreaded text editing and manual meshing.

I’d like to thank the class for their challenging questions and in-depth discussion of finite element modeling and analysis. To expand your own FEMAP and NX Nastran skills, visit us in Portland, Oregon for our next training on October 9th 2017.

SLIDESHOW:

ASME Section VIII, Division 2 "Design-by-Analysis" Pressure Vessel Consulting Services

We just finished two FEA consulting projects under ASME Section VIII, Div. 2 "Design-by-Analysis" code and they couldn't be more different. One was for the transport of electronic equipment within a gas line or a "pipe pig" and the other was a large high-temperature reactor using for the scrubbing of organic laden gases. The only commonality between the projects was that they had to pass the ASME pressure vessel code and our clients wanted their designs to be as efficient as possible. That is the beauty of ASME's design-by-analysis rules is that one only has to show that the structure meets their stress allowable within a broad list of available materials (Part D) or one can base the allowable on the material's ultimate strength. This flexibility allows one to leverage the full power of a finite element analysis to maximize the design of the structure. In the pipe pig analysis, we were able to cut weight out of the head and to allow our client to use a less costly, non-stainless steel material, In the 9.5m diameter reactor we optimized the manufacturing process to join the roof to the shell and performed a buckling analysis. Both projects saved our clients money in materials and construction costs and increased their confidence that they had the best approach going forward.

Another Femap and NX Nastran Class "In-the-Can"

Predictive Engineering finishes another Femap and NX Class at their office in Portland, OR. Students attended from Honda Aerospace, Endeavor Analysis, Boeing, Greenbrier Rail, Sierra Nevada Corporation and Moog CSA Engineering.

In the instructor feedback review, this review says: "Adrian is very knowledgable about the finite element process and Femap. Always had answers to questions and workshops were very good. Enough repetitiveness to help learn functions but not so much to make it monotonous. Much respect for Adrian." The overall scoring was silly high with only one "4" and the rest 5's. As the original developer of the class (me), I never got such high scores! Which has me thinking that I'll have to work to make the next class more challenging for the students such that the marks aren't quite as high.

We'll be having another Femap training session the week of October 19-23, please click the link for registration information, or contact us if you or your team needs training!
