LS-DYNA: Observations on Material Modeling

This is the 4th in a series of informal articles about one engineer’s usage of LS-DYNA to solve a variety of non-crash simulation problems. The first was on LS-DYNA: Observations on Implicit Analysis, the second was on LS-DYNA: Observations on Composite Modeling, and the third was LS-DYNA: Observations on Explicit Meshing.

As a former metallurgist whose specialty was structure-property relationships, I have a keen appreciation for how materials deform under load. At the federal lab where I worked, we had a lot of mechanical test equipment where I could break, crush and impact all sorts of things. This experience grounded me in my appreciation of how difficult it is to simulate the mechanical response of materials using some sort of X-Y plot of stress versus strain.

Implications of Siemens PLM Software's acquisition of CD-adapco

On Monday Jan. 26, 2016, German engineering company Siemens acquired U.S.-based CFD simulation software developer CD-adapco. This is a big coup for Siemens, since CD-adapco (Computational Dynamics-Analysis & Design Application Company Ltd) was the largest, privately owned CFD company in the world. We spoke with Predictive Engineering’s George Laird on the possible implications for the CFD services and consulting landscape.

Bjorn: Let’s jump in – will this change anything?

George: CD-adapco and more specifically Star CCM+ (computational continuum mechanics) has been the CFD metric against which other CFD codes are often measured. Having this code as part of the Siemens PLM Software family will allow us to have direct access for consulting service and sales.

Bjorn: Is there a downside for David getting swallowed by Goliath?

George: I’m a realist and I’m sure there is a bit of a downside, but the upside is that CD-adapco was a bit isolated as a niche CFD stand-alone company. By being part of Siemens PLM Software, they will have access to immense resources and a very professional worldwide technical support and sales infrastructure. For us, with our relationship with Applied CAx (a Siemens PLM Software reseller), we will have direct access to Star CCM+ and are very excited to start using it.

Bjorn: Okay – but what does it mean for the CFD analyst?

Upcoming PLM webinar for the simulation engineering community

This could be a good PLM webinar for the simulation engineering community. As PLM experts, our partners at Sherpa Design brought this to our attention and have recommended it. The webinar host, CIMData, is focused on the PLM market and provides multiple viewpoints into the PLM industry at large.

Their upcoming webinar will be on "Simulation Governance: Managing Simulation as a Strategic Capability." This topic could resonate with larger companies that have both engineering and analysis groups under the same roof.
