Taking the Expert out of CFD
Digital Manufacturing Report buried the essence of their article CFD for the Rest of Us in the very last paragraph where Intelligent Light’s Steve Legensky is quoted “[CFD] is no longer just an expert’s game.”
Dell also misses the boat a little bit in their take on this article, HPC in the Cloud Can Bring CFD to the Masses. While cloud-based high performance computing certainly improves access to resources they walk a fine line in saying “the Cloud” makes CFD more accessible to organizations “not interested in investing in staff with CFD expertise.”
In case you missed the news, Intelligent Light was recognized at SC12, the supercomputing conference, with the HPC Innovation Excellence Award for their efforts on improving CFD workflow as proven by the direct benefits realized by Zipp Speed Weaponry, a manufacture of bicycle wheels. Zipp’s new product line has been so successful the company added 120 jobs.
Intelligent Light’s multi-year study of CFD workflow and the application of that study to their FieldView product showed how advances in automatic meshing, on-demand CFD solvers, and efficient, remote extraction of engineering results from big data files can deliver the engineering insights Zipp’s engineers needed while minimizing the overhead typically associated with CFD.
I’ll nitpick Dell’s headline by pointing out that the masses don’t need CFD. And DMR’s headline gives me too much of an Oliver Twist vibe. I’ve said before that CFD is about process not processors, a sentiment that Legensky expresses much better. CFD used to be like a computer from the 1950s, a huge contraption tended to by legions of dedicated followers. CFD needs to be like a [dare I say] iPad, that you just pick up and use reliably.

Caveat: You still must understand and appreciate fluid dynamics before using CFD in the same way that you must understand (and maybe fear) electricity before rewiring your breaker box.

Wind Tunnel, Computer, Wind Tunnel
In the early, brash days of CFD it was going to replace the wind tunnel. [Depending on who you are, you are either making an embarrassed smile or a knowing chuckle right now.]
Turnabout is fair play. When you’ve got a souped-up computer (this one for cancer research) and a need for some serious cooling, why not build a wind tunnel around your computer?
Now, if you used that computer to do CFD on the flow through the wind tunnel and around your computer…
