Hi, Qucs as a project is stopped at the moment. I suggest you use Qucs-S, a very active project. On the other hand, you can use spice models directly. https://github.com/ra3xdh/qucs_s

Hi Thierry, Attached file with a correction, first select the qucsator simulator from "simulator settings..." then you must select "Pr1.I" from the data simulator. Greetings PS: It only works with the qucsator simulator.

Hi Thierry, I opened the diode file in Qucs-S, set up the "ngspice" motor simulator and ran it, the simulation finished fine. To see the diagram after the simulation, you need to take a "Cartesian" diagram of the component dock and place it on the schematic sheet (.sch). Remember to uncheck "open data visualization after simulation" (File>Document Settings...). I recommend updating the Qucs-s version to the latest version of Qucs-s 2.0.0. Please let me know if it helped you. Best regards CMAT

Hello, I think the problem is the ideal source of AC voltage. I am attaching a file with the ideal AC voltage source of version Qucs0.019 instead of Qucs0.0.20. In fact, I don't use Qucs as a simulator anymore because it's a stopped project. Now I use Qucs-S, you might want to give it a try. I hope it helps you.

hi everyone, To run correctly any simulations you need to use a ground reference. cheers
