The only reason this circuit oscillates is because of the variance of tolerances of the components. If you pair the transistors and capacitors and resistors it won't oscillate unless you take a wire and short a couple of legs of the transistors for a split second. (or discharge one capacitor and charge the other) This is a sample circuit in electronics training. In that one, an LED is placed above the collector of the transistors. This simulation might have a random variable in the algorithm to resemble the variances in component manufacturing. TinkerCad is another simulation online.
This is such a good tutorial. Could you make a tutorial how-to use a switch? Looks like something simple, but I see posts using a relay, which is strange.
How could one learn on their own that to get a better representation for certain simulations they can change an integration method from "trap" to "gear" (both terms I have no clue about)? Would you just have to get really lucky in a google search?
My (old school) advice would be: grab a book about SPICE simulation. A list of books is given here: ngspice.sourceforge.io/books.html . I would recommend the book by Tadej Tuma , Árpád Buermen. Also the book by Kielkowski directly answers your question. Hopefully there is a library near your place which offers such technical books.
Such a great tutorial, really appreciated this

I want to add DC 12 V to my schematic but after added it it dose not have a simulation model, how can I add a 12V dc sores to my schematic
I think you can use the pspice dc voltage for the simulation
