This series, despite being somewhat lengthy, is by no means a complete overview of the various methods, options and approaches to predicting component temperatures. Here is some stuff I didn’t cover… My bias in this series is towards the prediction of component temperature via simulation using a 3D CFD approach adopted in our (as ever) market leading FloTHERM and … [Read more...]

On the sliding scale of thermal component model representation king of all is a ‘detailed’ model. A 3D definition of all of the internal construction geometry and material properties does away with any of the accuracy inconsistency issues associated with the derived CTM (thermal resistor network type) approach. Despite the fact that all models are wrong a detailed … [Read more...]

Mentor’s Thermal Design Software Is The Best. OK, say’s who? It’s the conclusion from some independent research carried out by Aberdeen Research Group. Last time I showed that Aberdeen had found that Mentor’s customers are almost 3 times faster at completing thermal verification than users of other tools. Let’s take a look at why that is. Aberdeen found evidence of what users … [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, … [Read more...]

Like a river this blog series is slowing down due to its increased width and depth, that and a lot of travel on my part. So, let’s get it back on track! The previous blog focussed on the relatively well known 2 resistor compact thermal model (CTM) method, its strengths (simple to measure and describe) and its deficiencies (unconfirmed and inconsistent accuracy for … [Read more...]
