What Changed in CFD During 2013
It’s November and that means 2013 is virtually over. While some may take this opportunity to look forward to 2014, I’d like to look back at CFD in 2013: what will change? what will not on the CAE Watch blog published back on 31 Dec 2013.
#1. Automated mesh: a classical fairy tale continues.
Can’t argue with that. It’s the same old story. Literally, automated means “without human intervention.” I’m not aware of a mesher than can take any geometry file and generate a suitable mesh (one for which the CFD solution will converge to the right answer) without human intervention. Some would say they can do so given a clean CAD file which raises the issue that automation depends on when you start and stop counting. Some can say they can do so for a given application or even a given solver but automated meshing won’t help you if your solver doesn’t accept that particular type of meshing.
But if we stop being literal and start being practical you can find advances in many different software tools that automated, streamline, and otherwise make faster the job of mesh generation.
#2. CAD-embedded CFD: a placebo for democratization of CFD
He used the “d” word. I won’t take the bait.
#4. Lattice Boltzmann equation based CFD: not a game changer in 2013
All I’ll say here is that EXA’s stock price seems have doubled since April.
#5. Cloud computing for CFD or on-demand CFD: two turkeys do not make an eagle
I’ll address this one only because the turkey analogy makes me think of Thanksgiving. In my opinion, the issue with cloud computing is that it means different things to different people. Does it mean inexpensive? Fast? Automatic? Simple? The brave souls at the bleeding edge of this technology (Ciespace comes to mind) are going to have to do a lot of work, make a lot of mistakes and define the value proposition(s) for the rest of us.
#9. CFD software price: far from commoditization
Oh, he went there. Back to being literal: a commodity is “a class of goods which is supplied without qualitative differentiation.” I doubt any high technology field like CFD will ever be commoditized.
But that’s not the author meant. He mean cheap. CFD software is not cheap, like impulse buy cheap. However, you can get OpenFOAM for free and, from what I’ve seen it’s very capable especially in the right hands. Plus I’m told it’s the third most widely used CFD code on the planet.
Aha, we get to the crux of the matter. “Of course, almost all vendors will continue to enjoy high profit margin.” Excuse me while I go to the loading dock: our daily dump truck full of cash has arrived.
Seriously, you should read and think about all nine predictions. And maybe I should think about sticking my neck out and making predictions for 2014 instead riding someone else’s coat tails.
- Research and Markets published a forecast in which the global CAE market (which includes CFD) will experience a compound annual growth rate during the period 2012-2016 of 11.18%. [Accurate to two decimal places! It must be true!] That would make the market size US$3.4 billion in 2016.
- The same folks have a forecast just for the global CFD market in which it grows 13.33% over the same time period. No USD market size number provided.
- ANSYS had 2013 Q3 revenue of $212.7 million, an increase of 9% over the same period last year. This includes an operating profit margin of around 38%. They anticipate FY 2013 total revenue of around $860 million.
