John Parry Last time I promised I’d drill down into more detail about the difference between the CAD-integrated up-front approach to CFD and CAD-embedded Concurrent CFD. CAD-integrated CFD tools are essentially stand-alone tools launched from within the CAD system whereas Concurrent CFD is fully built into the CAD system. So what’s the real difference between the two? CAD-integrated CFD tools use the same approach … Read More

John Parry Back in June I posted ‘Air – Is it Running Out of Gas?’ and put forward the view that for general computing applications air isn’t running out of gas just yet. There are a couple of reasons for that. One is that I suspect the general public has concerns about leaks. Most people have passed cars stuck on the highway with a blown heater hose and seen water on the ground, and I’ve had an automotive water … Read More

John Parry I was on a conference call and WebEx yesterday with the NAFEMS CFD Working Group, of which Mentor Graphics is a member. One of the people on the call had a lot of background noise on his phone, which turned out to be a due to a fan by his desk to keep his computer cool. Computational Fluid Dynamics (CFD) is a memory hungry, CPU intensive activity so I guess he was running a fairly substantial case. … Read More

John Parry Some people think that because Concurrent CFD is so easy to use it must be simplistic. Nothing could be further from the truth. FloEFD has some very sophisticated physical models for cavitation, combustion, etc. plus by being CAD-embedded it’s also easy to use the CFD results to drive other simulation packages within the MCAD environment. Not limited to upfront design, Concurrent CFD can be used continuously … Read More

John Parry Using CAD-embedded CFD upfront and throughout the design process is the only way to go when it comes to compressing design schedules. We call this approach Concurrent CFD, as the CFD analysis can be done concurrently with design changes, taking upfront CFD to the next level. The product’s performance can be checked at each design iteration, leading to a more fluent CFD process that gives increased confidence … Read More

John Parry I’ve been getting some positive feedback on my previous posts on Concurrent CFD so I thought I’d continue with the thread. I’ve described traditional CFD, upfront CFD and concurrent CFD as very different entities - which they are, but I ought to point out that they represent the evolutionary spectrum of how the CFD technology itself has been packaged over the years. Partly this change results from … Read More

John Parry Me too, though being in the UK I tend to watch more Formula 1. As part of my job I often come across cool pieces of work done by our customers that we can’t publicise the work for reasons of confidentiality. This work by Voxdale is an exception though. It was done a couple of years back, not that long after Voxdale was founded, which makes it all the more impressive, and was done for Champ Car, now … Read More

John Parry As promised, here’s the second part of the explanation of why Concurrent CFD is different, or to use a cliché, a paradigm shift in CFD. The animation below looks more closely at why concurrent CFD is different to conventional and upfront CFD. By expanding the CFD process we can see it involves quite a number of steps. In going through the animation you will see that both conventional and upfront CFD … Read More

John Parry If you haven’t come across this short video, it gives a good overview of how FloEFD is blazing a path of least resistance so mechanical designers can streamline their workflow using Concurrent CFD – CFD embedded in the mechanical design environment. Note that it’s ONLY by embedding CFD within the MCAD tool that these time savings can be achieved, and FloEFD is the ONLY Concurrent CFD solution … Read More

John Parry While I was waiting for the last few people for my presentation ‘Thermal Design: A Key Part of the Electronics Design Flow’ at the UK Solutions Expo at the Heritage Motor Center in Gaydon a couple of weeks back I thought I’d poll the audience with a couple of questions. It’s rare that I get to speak to an audience of electronics engineers, so I was interested to see how they view thermal design. First … Read More

John Parry Some more thoughts on the fluent design vs. laminar flow analogy In my last post I used the example of an airfoil to illustrate a product design (object) that passes smoothly, or fluently through the design process (a fluid) without causing much turbulence (design rework) that otherwise disrupts the downstream flow (late in the design process) making the flow take longer to recover (increasing the … Read More
