This morning I again broke up the big reservoir capacitor into one reservoir capacitor for every SMPS, and this time the model remained happy. Aaaaand the results are in. LTSpice (with similar PTC and

Simulation of complex conductivity depending on frequency. See file Frequency-dependent_resistance.zip in TEMP folder.

I meant to say: -- Regards, Tony

Yes, of course that's true. Very strange that I never noticed before, as someone that uses a lot of underscore characters. Oh, well. Is the overbar NET notation old-fashioned? I use that a lot too, in

There doesn't seem to be any other easy way to produce characters with overbar. Most fonts don't have an alphabet of overbar characters. Of course, a different 'trigger' symbol other than underscore

It is unrelated to what the text is.? "LT" or "ADI" makes no difference.??The same thing happens if you write ".lib _foobar.lib". Yes it is deliberate in the sense that an underscore character in

It may be it's related (or not) to the feature that the "LT" text string in a symbol is magically converted to the old red LT corporate logo. They left that in while also adding the "ADI" string

Thinking again about it, I realized that the "topology check routine" throws a warning complaining that there is a cut-set made of (independent or controlled) current sources only. In this specific

So, does this mean the Windows service account does not know what LTspice is, or where to find it? Sorry, I don't know snakes. Andy

I thought that the advice was that it was not installed in the right place, but I might be wrong.'Not installed correctly' might be a paraphrase of 'I can't open it'. -- This email has been checked

I believe I am doing this

Thank you, the application is clearly installed correctly though because it works when not running as a service

You'll need to launch the python LTspice subprocess in the context of the target user and target schematic source folder.

I think it would make a difference because the solver has to determine additional unknowns with more capacitors, namely the current through each individual capacitor. There are no additional nodes,

Convert the error number to hex. Then Google is your friend. The Windows error code 0xc0000409 is a software exception error that can occur when an application is installed incorrectly Sent: Thursday,

Yes it is a windows error, something about a stack buffer overrun, not sure what to make of that. The message "Simulation failed with status code <status code>" Is my code in the except block of the

Yes...its minor and cosmetic. But if it were me I would have fixed it a long time ago.

It's been around for a very long time.? A decade or two?? I think there would be no reason for them to pick up on that one particular thing that has been there for so many years, unless somebody

Presumably that is a Windows status code.? I think it did not come from LTspice, but it might mean Windows is telling you that LTspice did not exit happily. Can you find what that error code means,
