Something interesting about the lossy_inductor.sch:
One can use the variable ‘freq’, which seems to be defined by QS itself.  But only, if the equation block has Export=no and if the resulting parameter is used in a “equation based component in frequency domain”
Sadly I cannot find a reference to this ‘freq’ variable in the QS F1 help .

You could define all components in the coilcraft model by a separate “equation based component in frequency domain”. Writing down the e.g. z parameters of a capacitor/inductor/resistor should be easy. But maybe its problematic in case you want to use the resulting inductor model without ground connection on either side.

Coilcraft also offers touchstone file models. Maybe that’s an option.

Hi,

did you solve the problem in the meanwhile?

I’m unfamiliar with the qs em simulation. It could help, if you setup a very minimalistic example that shows your problem. You can package the qs project with Project -> create package and upload the file here.

I researched a bit:

CST Schematic view:
zoom with mouse wheel (turn wheel ‘away’ from user = zoom out)
move with mouse wheel /middle button press
context menu with right button click

CorelDraw2019:
zoom with mouse wheel (turn wheel ‘away’ from user = zoom in)
move with mouse wheel /middle button press
context menu with right button click

Excel365:
zoom with CTRL + mouse wheel (turn wheel ‘away’ from user = zoom in)
move with mouse wheel /middle button press
context menu with right button click

Firefox
zoom with CTRL + mouse wheel (turn wheel ‘away’ from user = zoom in)
context menu with right button click

Rhino-ceros CAD v5
zoom with mouse wheel (turn wheel ‘away’ from user = zoom in)
move with right mouse button press
context menu with mouse wheel /middle button press

KiCad 6
zoom with mouse wheel (turn wheel ‘away’ from user = zoom in)
move with right mouse button press
context menu with right button click

I don’t see any argument against your plan.
Additionally I suggest making sure to set “turn wheel away from user = zoom in”

I like it.

Ah, yes. Thank you!

BTW: For a one port device, rtoz and stoz are the same.

This old forum post: https://qucsstudio.de/forums/topic/tutorial/
refers to the “formula” item in the diagrams folder. Is stoz() meant to work with that?

Hi Henning,

It sounds you are referring to Qucs. This forum is about QucsStudio, see http://qucsstudio.de/about/

Its very unlikely that you will find help here.

Best

Carsten

How do I attach a .sch file to my post? I get an error “Sorry, this file type is not permitted for security reasons.” But others here in the forum seemingly managed to do it.
