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

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

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

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

Happy New Year everyone. I hope it’s a prosperous and peaceful year for both you and your company. As promised, here’s a Flash animation showing the difference between traditional CFD, upfront CFD and concurrent CFD which needs some introduction. In traditional CFD, the model geometry is first exported from the CAD system. That’s the easy part. The geometry then needs to be re-imported into the CFD … Read More

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

It could save your company a shed load of time and money… Interested? OK, here’s some research by Aberdeen Group, which I presented at several of the recent Solutions Expos. First off, the Mechanical Analysis Division’s customers choose Mentor’s tools because they recognise them as being the best. They don’t just make do with tools available as part of another software suite, as shown below in the … Read More

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

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
