Hey, I’m the guy who asked the original question https://forum.kicad.info/t/timestep-too-small-error-in-simulation/51164, on top of which you intially posted yours.
The Op-amp model you got is probably fine. That said, I’ll attach the one I used successfully in my original question, maybe it’s of some help to you. But that wasn’t the problem in my case.
In my case, I had pin assignments wrong for some other component altogether (the NPN BJT, I think). Check that carefully for all of your components, even the tiny ones.
If it’s not clear what we mean by pin assignments, we’re talking about the following page in the component’s simulation properties. You can set up which pin numbers of the symbol correspond to which pin numbers of the simulation .lib file by modifying the table in the top half of the dialog box.
If you share your project files (including any libraries and stuff that you may have added), I’d be happy to check it out in KiCAD. But please check your pin assignments first.
