Equivalent mechanical system for a simple filter

It's probably a behavioral-model-based system simulator. I regularly write my own behavioral models to substitute for complex slow-simulating device-level stuff.

I do that in PSpice. LTspice is similar enough that I would guess you can do it there as well.

NL5 is a "Cirucit" simulator, which probably makes it faster ;-)

Question for NL5 author: Are your models text-based?

...Jim Thompson

The unanswered question is really how to simulate the series inductor, in a pi CLC circuit, as its mechanical counterpart.

Chris

Part of the point that i was trying to make is that the springs should go to reference (like the caps), not series. Doing so leaves no reasonable connection for mass (mass is not a two terminal kind of thing, unlike an inductor).

Electricity-to-heat analogy?

Capacitor =3D heat capacity Resistor =3D thermal resistance (1 / "thermal conductance") Current =3D heat flow Voltage =3D temperature

Thanks, Alexei.

It is still fast even as "Circuit"... already fixed :)

It's normal graphical schematic entry. Usiing common ad terms: "interactive, easy to use, highly intuitive, .." etc.

Thakns, Alexei.

Inductor =3D ?????? ;-)

You've already answered: ;-) No inductors, no diodes, no transformers... Heat is so simple! Not talking about convection though...

And what models to inductance?

Then it is too simple to do the modeling that is needed.

"Thermal mass"?

Hope This Helps! Rich

heat

That's a capacitor.
