Please don't be discouraged by these repeated appeals for help, Alexander. New members do not know where to search for advice, and some members hope to avoid searching by asking for advice here. That does not devalue your very helpful contributions to our group.

I have repeatedly shown how it is quite simple to model transformers with cores with hysteresis loops. I posted the models on LTwiki.  I have many examples of circuit calculation. It surprises me that my achievements are not noticed. I used cores with Chan and Gilius-Atherton models. Also powder cores.

Type in Google: bordodynov LTspice and you will immediately receive the desired link.
