QUCSBased on our record, Insight Maker should be more popular than QUCS. It has been mentiond 3 times since March 2021. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
If you can get s parameter model you can use that. There are also generic transformer and coupled line models so long as you've got a way of characterising it you should be able to model it. https://sourceforge.net/projects/qucs/. Source: over 1 year ago
I'm looking into free to use online simulation and collaboration software such as https://insightmaker.com/ and will start digging into it. Source: over 1 year ago
I created a fairly popular system dynamics modeling applications back when I was a grad student [0]. When using modeling tools like system dynamics, it's useful to keep in mind George Box's quote that "All models are wrong, but some are useful". When using a modeling tool to describe any form of social system you're creating an imperfect copy of it. This imperfect copy embeds what the modeler (rightly or wrongly)... - Source: Hacker News / over 1 year ago
Some other commenters here seem to think this article is (or should have been?) an introduction to systems thinking, or an argument for using it. The article is explicitly framed as some advice, based in experience, on avoiding common pitfalls with using explicit models in systems thinking. As such I think it is a nice read. It is also full of links to other interesting work by the author, not least of which is a... - Source: Hacker News / over 2 years ago
