KiCad Simulation problem

Schematic Simulation (Ngspice)
21

I downloaded your 7z-file (PE1542_7V_2.7z) and opened in KiCad (Nightly, but in this case it should behave the same as version 7.0).

Several of the Spice model files set in the symbol properties are missing in the 7z-file. For example the ones for the diodes, zener diodes and the BCY59 and 2n3055 transistors are not present.
It seems also, that in preparing for sharing the project, it would be good to take all the necessary model files and copy them into the project folder, and then attatch them in the symbol properties from there. Thus, when the zip-file is unzipped, KiCad will search for the models in the project folder and find them there, instead of trying to search in C:\MC12\LIBRARY\ which only exists on your computer and not on the computer where the recepient of the shared project unpacks the zipped project.

These are the error messages I get for missing and not found simulation model files:

Holger,
Thank you, will correct.
Does this mean that the ua723 worked well in your simulation ?

No, the simulation did not start due to the buggy RG59U input.

Hi Holger,
It works now :smiley: , thank you for your help.
Main problems were ua723, Diode bridge, diodes, bcy59…models were unreliable.
I attached the zip file, so you can run it too…if you want.
Not sure about the detailed results yet (ua723), will see if it provides accurate values…
Again, thank you for your help, you pointed me in the right direction, where to look…For a non experienced simulator user, it is a bit confusing.
Have attached also the different transistors, diode, ua723 models, now taken from my application directory. …in a zip ( :smiley:) file.

please let me know how to close the request.
