Using circuit simulator in other disciplines

Here is an example of using NL5 for simulation in other disciplines using electrical analogy principle. If you know differential equations for the process - mechanical, heat transfer, fluid flow, whatever - and you know at least basics of electricity, it's not going to be much of a problem to find a correlation between two. Having simple ideal components, where none of parameters are hidden "under the hood" and component behaviour is clear and predicted - is absolutely required. And that's why NL5 is good for this type of analysis.
