Robin Bornoff The temperature rise that electronic components attain in operation is due to 3 things. The power that they dissipate, the ambient temperature surrounding the product and the various thermal bottlenecks that the heat passes through on its journey from the source to the ambient. An accurate simulation requires all 3 aspects to be modelled correctly. In terms of the bottlenecks, conductive resistance … Read More

Robin Bornoff Before you sell it, or commission it, you want to be sure that it works. Monies have been spent on getting things this far, some of it on you via your overhead and your expansive salary (yeh, ok, I hear you). Expectation is that your organisation will make more money back. Last thing you want is to have your product fail, have to be tweaked, fixed, respun, redesigned or canned. What you’d like … Read More

Data Center Presentation at ASME in Texas

Posted by Travis Mikjaniec

Travis Mikjaniec Hello Everyone This is a bit of a follow up to my previous blog about the FloVENT analysis of the Mentor Graphics Data Centers in Wilsonville, OR and Shannon, Ireland.  http://www.mentor.com/products/mechanical/blog/post/mentor-graphics-data-center-design-using-cfd-modeling-fc6dbfc3-ec40-431a-8628-67375c2e946a Well the one in Shannon, Ireland has been online for a while now, and our Wilsonville, OR data … Read More

Travis Mikjaniec Hello Everybody   Previously, I co-authored a semitherm paper on the use of our HVAC CFD tool, FloVENT, on the design of a Mentor Graphics data center.  Recently I have seen this topic republished in the data center journal with the title “EDA Vendor takes its Own Advice on Data Center Design”.  I find this topic interesting, so I thought I’d blog about this and break from my typical … Read More

Shrink It and Pink It

Posted by Nazita Saye

Nazita Saye I’ve never really been a fan of the color pink. If you look thru my childhood pictures you’ll find me wearing pink clothes (chosen by my lovely mom) but in every one of those pictures you also find my head slightly dipped down, defiantly looking into the camera and pouting. Not a happy bunny. As soon as I was old enough to make my own decisions regarding clothes, pink was banished from my wardrobe. … Read More

Flying High

Posted by Nazita Saye

Nazita Saye When I used to work in San Francisco, I had a lovely office. My window had a breath taking view of the Bay Bridge (this is while the Gap HQ building was under construction so I had a completely unhindered view of the bridge and the bay). One day I was sitting at my desk when I noticed something moving fast out of the corner of my eye. I looked up from my screen to see the magnificent Blue Angels announcing … Read More

Liberating Human Potential

Posted by Nazita Saye

Nazita Saye I was reading an article in City A.M a while back – a freebie newspaper containing banking and business news and distributed to those lucky souls in London who take public transport. On this wet and cold morning no one was interested in taking a copy so as I walked by the guy handing them out, I stuck out my hand. I wasn’t expecting much but it was better than staring into nothingness (as you do on … Read More

Stand Up and Be Heard

Posted by Nazita Saye

Nazita Saye When was the last time someone asked for your opinion at work? I don’t mean “where should we go for lunch” type of question. I mean the type where someone really wants to know what you think about something. Being a talkative and opinionated sort, whenever someone asks me a question I’m perfectly happy answering them.  Most of the time when this question is posed to me it’s about projects but sometimes … Read More

"Why Cartesian Grids Are Good"

Posted by Robin Bornoff

Robin Bornoff I put the title in quotes as it’s the title of a blog post by John Chawner at Pointwise who keeps a pleasantly vendor neutral(ish) blog about all things CFD called ‘Another Fine Mesh’, including the excellent weekly ‘This Week in CFD’ that is becoming a bit of a mecca for the CFD community. John’s blog focusses on a white paper Mentor issued recently about How to … Read More

Here Comes the Rain Again

Posted by Nazita Saye

Nazita Saye Saturday lulled me into a false sense of security. The weather was absolutely gorgeous and for once in a long time I wasn’t out hiking.  I thought that’s fine… there’s always tomorrow. Then bam on Sunday the rain came … the monsoon kind of rain. It reminded me of a quick conversation I had with a German friend of mine over the summer.  He quipped that if rain were an Olympic event, GB would win Gold, … Read More

Sum of the Parts is Greater

Posted by Nazita Saye

Nazita Saye I live in a 3D world –3D simulation that is.  I remember when my work life went from 2D to 3D. I used to sit in a cubicle across from a software developer who specialized in graphics. He was a pesky lad. Whenever he’d get stuck on a particularly difficult piece of code he would throw missiles of all kinds at me – anything from crumpled pieces of paper to rubber bands and paper clips. I don’t know why … Read More

Robin Bornoff Effective use of a Computational Fluid Dynamics (CFD) simulation tool requires at least a working knowledge of fluid dynamics itself. Tools alone don’t make for a good engineer. When interviewing for jobs within the Mechanical Analysis Division (and way back into Flomerics days too) a common question posed to tease out such an understanding is to describe the air flow patterns in and around a … Read More

And then the announcer said...

Posted by Nazita Saye

Nazita Saye I don’t know about you but last Saturday night I decided to stay in – I was only halfway done with my weekend but I was exhausted. The day before I had taken a vacation day and driven down to Weymouth to watch Olympic sailing and got up super early to drive back to London to do an 8-mile hike in Surrey. So the thought of going anywhere or doing anything too taxing was out of the question (especially … Read More

CFD and the Olympics

Posted by Travis Mikjaniec

Travis Mikjaniec When I watched the opening ceremonies of the Olympics, I knew I needed to analyze something related to the Olympics during this special time of year.  At first I thought I would analyze the Olympic Rings.  Not a real scientific CFD analysis, but just something cool and easy to do, by hollowing out some Olympic CAD rings and putting some flow through.  Well, using FloEFD to do this analysis was easy, … Read More

Robin Bornoff One thing the Mechanical Analysis Division is not guilty of is vendor hubris. Despite the passion we have about our CFD based simulation solutions we know our place, especially in terms of where best to apply our solutions throughout the design process. CFD is a very powerful tool to predict 3D heat air flow and heat transfer but it certainly isn’t the only approach. As is common in both electronics … Read More
