Simulating zig zag transformer produces DC output!

[Circlotron]

Using Simetrix to try and simulate a zig zag transformer. If I simply wire it up as per normal I get huge circulating currents in two of the phases. If I put a 10 ohm resistor in the wires that go to ground, one of the wires has zero current and the other two have opposite polarity DC currents, or so the simulator says. I've spent several hours on this and I can't get it right. Any ideas?

Try setting the sources initially to zero?

Yep, that was it. Phase A was starting at the zero crossing but the other naturally were not. Now B starts 6.66mS after A, and C a further 6.66mS. i had to put 1mR current limiting resistors in series with the sources otherwise the simulator got upset. Now it seems to work. Now to try it out with that three phase rectifier ripple cancelling idea! Thanks Tim.
