The ability of FloTHERM to resolve a massive disparity in geometric length scale in a single model is for me its greatest strength. By not having to make simplifying assumptions to ignore either extremely small or truncate extremely large geometric parts and features, simulation accuracy can be better assured. The ‘die in a city’ model in the previous blog resolved … [Read more...]

Electronics are small and getting smaller. The world in which we live is tending to stay at the same size. The one thing that typifies electronic thermal simulation models is the disparity of length scale that has to be accommodated. FloTHERM has been evolved to handle this disparity for over 20 years.  I, my fellow FloTHERM apostles and hopefully the FloTHERM userbase … [Read more...]

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...]
