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.

Introducing the LS-DYNA MPP Program Manager

Predictive Engineering is pleased to introduce our LS-DYNA MPP Windows Interface. We built this for our own LS-DYNA consulting project work and we realized others may enjoy it also. The program has been featured on TenLinks, a news distribution service for the CAD, CAM and CAE industry.

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.
