Try modeling the FET to ground with the diode, in the traditional flyback style. I haven't tested but I think on the secondary you'll get a pulse that keeps growing, which may flatten off if you saturate your transformer, followed by a sharp, deep drop as the FET cuts off and the diode opens.
I think you wanted a sine wave on the far side, didn't you? Then you'd need to drive a clean-ish sine wave on the primary, probably with a bridge-tied load to reach the desired amplitude, or you'd need to make clean dc on the secondary in the traditional flyback style and use some high-voltage transistors to shape your wave there.
