Basics of Composite Analysis for Engineers

At our Seattle FEMAP Symposium, George Laird from Predictive Engineering presented a brief on "Basics of Composite Analysis for Engineers."

It focuses on the underlying basis of how composites function, and shows how this ties to simple and verifiable simulation models that can be easily validated for common engineering applications. The idea is to provide a roadmap on how one can idealized a structure into a composite model and have confidence that the final FEA results will validate. We view this as a multi-step process, that with a little bit of thinking will save a lot of hard work. Starting with some basics we’ll carry an example analysis forward toward final validation.

As George puts in the intro: “Once you remove a bit of the fear, uncertainty and doubt about composite simulation, building accurate first order FEM’s is pretty basic.”

We're included a link to George's presentation, as well as video of a related simulation showing decompression of composite container.

Looking forward to two great upcoming FEA events

It's been busy here at Predictive Engineering. We finished holding two great training courses, our FEMAP training with a talented group of engineers, and our high-value LS-DYNA training with another outstanding group of engineers.

At the same time, we've kept up with great projects for our clients, including a broad-spectrum stress and vibration analysis of large composite container.

Two upcoming events were looking forward to:

If you're at either event, reach out to us and say "hello!"

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?
