I'm trying to simulate a model of a 3-phase transformer in LTspice.

My first attempt with different K values worked, but it didn't include the core saturation.

Now I tried to built a new model with the help of the example from [analog spiceman][1] in the LTspice group.

The problem with my model is that it has 3 primary windings and 18 secondary windings on a E-core. The primary is connected in delta and the secondary are connected in star. Also it has B6 bridge rectifier on the secondary side with a high capacity bank.

For the first attempt of the new model, I tried to make it simple. That's why I put all the secondary windings for each transformer leg together. My problem now is that the simulation runs through, but the plot only shows some ms of the simulation in .trans

Maybe someone has got a tip for me?
