Future World

Posted by Nazita Saye

Nazita Saye One of my recent social media feeds hit me like a ton of bricks over the weekend. “Yesterday belongs to the past. Tomorrow is the future. Today is a gift – that’s why it’s called the present” (Bill Keane). I sat there blinking at it for a while letting the thought sink in. You see I recently had discovered that while out walking some 600+ miles around the English countryside over the past couple … Read More

SOS for System-Level Design

Posted by Nazita Saye

Nazita Saye I knew something was up when I was driving home last night. It took me 60 minutes to go 3 miles. In other words, traffic was flowing way slower than normal. I got to the Teddington/Kingston roundabout and noticed that the road going to Teddington had been shut due to emergency roadworks. So most of the traffic that went through Kingston and headed to points north needed to be diverted. In other words: … Read More

How to Guides

Posted by Nazita Saye

Nazita Saye I’d like to think of myself as a pretty competent person – throw a problem at me, I’ll find a solution for it. Case in point. Last week I noticed some cracks suddenly appearing in the kitchen walls and ceiling. The kitchen sits directly underneath the bathroom. The cracks looked like they were appearing where the bathtub was located and they felt damp. Doesn’t take Sherlock Holmes to deduce this … Read More

John Parry SEMI-THERM is one of the premier thermal management conferences and has the most targeted exhibition by far, with some 40+ exhibitors, including Mentor Graphics as Platinum Sponsor, so it’s a great place to network with people in the ‘cooling business’. The exhibition is FREE TO ATTEND, so if you’re in the bay area and interested in thermal management stop by and see us at the DoubleTree Hotel and … Read More

Robin Bornoff Electronic products, and products that contain electronics, are typified by being constructed of 100s if not 1000s of individual parts. A CPU alone is the most complex manufactured product on earth as demonstrated in this excellent picture story on Tom's Hardware. From the IC through package, PCB and chassis, items are glued, cured, soldered, screwed and assembled into the myriad of products that run … Read More

What is Fluid Thinking?

Posted by Doug Kolak

Doug Kolak Do you know someone who had issues with an automobile overheating or an issue with a sump pump?  What about someone who has flown on an aircraft or even used electricity?   If I had to take a not so wild guess, I would bet that most people out there with the ability to read a blog post would answer yes to at least one of these questions.  This is good because it means you have at least indirectly … Read More

Robin Bornoff FloTHERM V10 is a major release that marks 25 years as the leading electronics thermal simulation tool. This series will introduce the top 10 features that we've delivered, hopefully giving some insights not just on the features themselves, but also on the background as to how and why we've developed them. To start with let's look at the most obvious change, a new graphical user interface (GUI). … Read More

Robin Bornoff The latest release of FloTHERM, V10, is now available! It is a major release, satisfying over 40 software enhancement requests as posted and voted on by the FloTHERM userbase on the Mentor IDEAS site. The release addresses user feedback regarding pre-processing model definition and debugging, vastly improves the performance of the CFD solver, extends FloTHERM’s transient simulation capability … Read More

Robin Bornoff Simulation should never be done for its own sake. 3D computational simulation is still a relatively young technology in the grand scheme of things, akin to the automotive industry of 100 years ago where drivers were more like engineers, they had to be to use the car. Coming up with a design solution is analogous to getting to your destination in a car, it’s also quicker than walking. That’s … Read More

Things I learned in 2013

Posted by Nazita Saye

Nazita Saye Sharon, one of my friends, jokingly (but with a sinister tone in her voice) calls me the List Maker. And it’s true. Somehow making lists and crossing out items makes me feel a bit more in control of my life where the only theme is constant change. On the first day of my Christmas vacation I made a list of everything that I needed to do around the house… stuff that is time-consuming and requires more … Read More

Robin Bornoff Have you ever wondered why, after a winter night, some of your car windows are iced over whilst others are not? Happens after a clear night with no clouds. To understand the reason one must appreciate the fact that something loses heat, and thus gets cold, for two reasons; losing heat to the local air by convection and losing heat to any colder surrounding object due to thermal radiation. On a cold … Read More

Robin Bornoff It’s always nice to get some comments on your blog. When starting writing blogs about 4 years ago I was told that so long as you write about something that you’re interested in, then others will read it. Comments are the echo to what otherwise would be a Demosthenes type shouting at a roaring sea of disinterest. So when a colleague here at Mentor, Dave Roberts, commented on Part 3 of this … Read More

Robin Bornoff Dylan in his original YouTube video made the point that the tea lights only burn for about 4 hours and that he replaces them after the morning burn for an afternoon warm up session. At 1p per candle, 1p/~35W, we shouldn’t lose sight of how cost effective this heating method is. There is some doubt as to the actual power dissipation for each candle but this approach is scalable, if a 4 candle arrangement … Read More

Robin Bornoff We often do things that we intuitively feel are beneficial, often without realising just why. One of the beauties of simulation is its ability to provide insight into a physical phenomena or design. Sometimes described a a computational experiment, simulation can do more, and more easily, in terms of ‘measuring’ a system. I’ve applied this advantage to help describe why putting a couple … Read More

Robin Bornoff Dylan Winter, boat owner, film maker and blogger, made a youtube video about a year ago showing how four tealights (small candles) can be used to warm up a small well insulated home office. A couple of weeks ago the video went viral, now having ranked up nearly 2.5 millions views. A couple of friends pinged me to see if I could help explain why this apparent miracle in home heating worked. Some pacing … Read More
