Three Phase Transformer

[Shadow_warrior]

Hello, I want to simulate a 3 phase YD1 (star Delta) transformer in LTSpice, but the output of secondary transformer( Delta SIde is not coming properly). Can please someone check where I am doing wrong?
Attached is the LTSpice file.
Thanks in advance.

Where or what defines the magnetic coupling between the 6 windings? As of now, they are just independent inductors.

I think I did something wrong but I am getting power through the transformer.

Also I found some startup problems that seem better when you "skip initial operating point solution:"

The basic construction of a three phase transformer is three single phase versions mounted on the same lamination, in fact it is very easy to make one from three identical single phase types.
